28 Take heed, therefore, to yourselves, and to all the flock, in which the Holy Spirit has made you overseers, to shepherd the assembly of the Lord and God which he purchased with his own blood.

Take heed, therefore. He doth now apply his speech unto them, and by many reasons showeth that they must watch diligently, and that he is not so careful but because necessity doth so require. The first reason is, because they be bound to the flock over which they be set. The second, because they were called unto this function not by mortal man, but by the Holy Ghost. The third, because it is no small honor to govern the Church of God. The fourth, because the Lord did declare by an evident testimony what account he doth make of the Church, seeing that he hath redeemed it with his blood. As touching the first, he doth not only command them to take heed to the flock, but first to themselves. For that man will never be careful for the salvation of other men who will neglect his own. And in vain shall that man prick forward other to live godlily, who will himself show no desire of godliness. Yea, that man will not take pains with his flock who forgetteth himself, seeing he is a part of the flock. Therefore, to the end they may be careful for the flock to them committed, Paul commandeth and warneth that every one of them keep himself in the fear of God. For by this means it should come to pass, that every one should be as faithful towards his flock as he ought. For we said that Paul reasoneth from their calling, that they be bound to take pains in the Church of God, whereof they have the government. As if he should say, that they may not do whatsoever they like best, neither are they free after they be made pastors, but they be bound publicly to all the flock. The Holy Ghost hath made you overseers. By the very word he putteth them in mind, that they be placed, as it were, in a watch-tower, that they may watch for the common safety of all men. But Paul standeth principally upon this, that they were not appointed by men, but the charge of the Church was committed unto them by God. For which cause they must be the more diligent and careful, because they must give a straight account before that high seat of judgment. For the more excellent the dignity of that Lord and Master whom we serve is, the more reverence do we give him naturally, and the reverence itself doth sharpen our study and diligence. Moreover, though the Lord would have ministers of the word chosen from the beginning by the voices [suffrages] of men, yet doth he always challenge the government of the Church to himself, not only to the end we may acknowledge him to be the only governor thereof, but also know that the incomparable treasure of salvation doth come from him alone. For he is robbed of his glory if we think that the gospel is brought unto us, either by chance or by the will of men, or their industry. But this doth Paul attribute peculiarly to the Spirit, by whom God doth govern his Church, and who is to every man a secret witness of his calling in his own conscience. Concerning the word overseer or bishop, we must briefly note this, that Paul calleth all the elders of Ephesus by this name, as well one as other. [1] Whence we gather, that according to the use of the Scripture bishops differ nothing from elders. But that it came to pass through vice and corruption, that those who were chief in every city began to be called bishops. I call it corruption, not because it is evil that some one man should be chief in every college or company; but because this boldness is intolerable, when men, by wresting the names of the Scripture unto their custom, doubt not to change the tongue of the Holy Ghost. To govern the Church. The Greek word poimainein doth signify to feed. But by a fit similitude it is translated unto every kind of government. And we have said that this is the third argument drawn from the excellency of the function; as the same Paul telleth Timotheus elsewhere, that he take heed and see how he ought to behave himself in the house of God, which is the Church of the living God, the pillar and ground of truth. As if he should say, that there is no time to be idle in such a weighty calling, and that those are less excusable whom God hath made stewards of his family, the higher that degree of honor is, unless they be correspondent to so great dignity, that is, unless they do their duty diligently. Now, if bishops or overseers be made by the Holy Ghost, to the end they may feed the Church, the hierarchy of Papistry is ridiculous, wherein bishops being proud of their (painted sheath and) vain title, do not so much as once meddle with the function of teaching, no, not for fashion's sake. Which he hath purchased. The four reasons, whereby Paul doth carefully prick forward the pastors to do their duty diligently, because the Lord hath given no small pledge of his love toward the Church in shedding his own blood for it. Whereby it appeareth how precious it is to him; and surely there is nothing which ought more vehemently to urge pastors to do their duty joyfully, than if they consider that the price of the blood of Christ is committed to them. For hereupon it followeth, that unless they take pains in the Church, the lost souls are not only imputed to them, but they be also guilty of sacrilege, because they have profaned the holy blood of the Son of God, and have made the redemption gotten by him to be of none effect, so much as in them lieth. And this is a most cruel offense, if, through our sluggishness, the death of Christ do not only become vile or base, but the fruit thereof be also abolished and perish; and it is said that God hath purchased the Church, to the end we may know that he would have it remain wholly to himself, because it is meet and right that he possess those whom he hath redeemed. Notwithstanding, we must also remember, that all mankind are the bond-slaves of Satan until Christ set us free from his tyranny, gathering us into the inheritance of his Father. But because the speech which Paul useth seemeth to be somewhat hard, we must see in what sense he saith that God purchased the Church with his blood. For nothing is more absurd than to feign or imagine God to be mortal or to have a body. But in this speech he commendeth the unity of person in Christ; for because there be distinct natures in Christ, the Scripture cloth sometimes recite that apart by itself which is proper to either. But when it setteth God before us made manifest in the flesh, it doth not separate the human nature from the Godhead. Notwithstanding, because again two natures are so united in Christ, that they make one person, that is improperly translated sometimes unto the one, which doth truly and in deed belong to the other, as in this place Paul doth attribute blood to God; because the man Jesus Christ, who shed his blood for us, was also God. This manner of speaking is caned, of the old writers, communicatio idiomatum, because the property of the one nature is applied to the other. And I said that by this means is manifestly expressed one person of Christ, lest we imagine him to be double, which Nestorius did in times past attempt; and yet for all this we must not imagine a confusion of the two natures which Eutychus went about to bring in, or which the Spanish dog, Servetus, hath at this time invented, who maketh the Godhead of Christ nothing else but a form or image of the human nature, which he dreameth to have always shined in God.
1 - "Indifferenter," indifferently.
Take heed, therefore - Attend to; be on your guard against the dangers which beset you, and seek to discharge your duty with fidelity.
Unto yourselves - To your own piety, opinions, and mode of life. This is the first duty of a minister; for without this all his preaching will be vain. Compare Colossians 4:17; 1-Timothy 4:14. Ministers are beset with unique dangers and temptations, and against them they should be on their guard. In addition to the temptations which they have in common with other people, they are exposed to those special to their office - arising from flattery, and ambition, and despondency, and worldly-mindedness. And just in proportion to the importance of their office is the importance of the injunction of Paul, to take heed to themselves.
And to all the flock - The church; the charge entrusted to them. The church of Christ is often compared to a flock. See the John 10:1-20 notes; also John 21:15-17 notes. The word "flock" here refers particularly to the church, and not to the congregation in general, for it is represented to be what was purchased with the blood of the atonement. The command here is:
(1) To take heed to the church; that is, to instruct, teach, and guide it; to guard it from enemies Acts 20:29, and to make it their special object to promote its welfare.
(2) to take heed to all the flock the rich and the poor, the bond and the free, the old and the young. It is the duty of ministers to seek to promote the welfare of each individual of their charge not to pass by the poor because they are poor, and not to be afraid of the rich because they are rich. A shepherd regards the I interest of the tenderest of the fold as much as the strongest; and a faithful minister will seek to advance the interest of all. To do this he should know all his people; should be acquainted, as far as possible, with their unique needs, character, and dangers, and should devote himself to their welfare as his first and main employment.
Over the which the Holy Ghost - Though they had been appointed, doubtless, by the church, or by the apostles, yet it is here represented as having been done by the Holy Spirit. It was by him:
(1) Because he had called and qualified them for their work; and,
(2) Because they had been set apart in accordance with his direction and will.
Overseers - ἐπισκόπους episkopous. "Bishops." The word properly denotes those who are appointed "to oversee or inspect anything." This passage proves that the name "bishop" was applicable to elders; that in the time of the apostles, the name "bishop" and "presbyter," or "elder," was given to the same class of officers, and, of course, that there was no distinction between them. One term was originally used to denote "office," the other term denotes "age," and both words were applied to the same persons in the congregation. The same thing occurs in Titus 1:5-7, where those who in Titus 1:5 are called "elders," are in Titus 1:7 called "bishops." See also 1-Timothy 3:1-10; Philippians 1:1.
To feed - ποιμαίνειν poimainein. This word is properly applied to the care which a shepherd exercises over his flock. See the notes on John 21:15-16. It is applicable not only to the act of feeding a flock, but also to that of protecting, guiding, and guarding it. It here denotes not merely the "duty" of instructing the church, but also of "governing" it; of "securing" it from enemies Acts 20:29, and of "directing" its affairs so as to promote its edification and peace.
The church of God - This is one of three passages in the New Testament in regard to which there has been a long controversy among critics, which is not yet determined. The controversy is, whether is this the correct and genuine reading. The other two passages are, 1-Timothy 3:16, and 1-John 5:7. The mss. and versions here exhibit three readings: "the church of God" τοῦ Θεός tou Theos the church of the Lord τοῦ Κυρίου tou Kuriou; and the church of the Lord and God Κυρίος καὶ Θεός Kurios kai Theos. The Latin Vulgate reads it "God." The Syriac, "the Lord." The Arabic, "the Lord God." The Ethiopic, "the Christian family of God." The reading which now occurs in our text is found in no ancient mss. except the Vatican Codex, and occurs nowhere among the writings of the fathers except in Athanasius, in regard to whom also there is a various reading.
It is retained, however, by Beza, Mill, and Whitby as the genuine reading. The most ancient mss., and the best, read "the church of the Lord," and this probably was the genuine text. It has been adopted by Griesbach and Wetstein; and many important reasons may be given why it should be retained. See those reasons stated at length in Kuinoel "in loco"; see also Griesbach and Wetstein. It may be remarked, that a change from Lord to God might easily be made in the transcribing, for in ancient mss. the words are not written at length, but are abbreviated. Thus, the name Christ Χριστός Christos is written ChoS; the name God θεός theos is written ThoS; the name Lord κύριος kurios is written KOS; and a mistake, therefore, of a single letter would lead to the variations observable in the manuscripts. Compare in this place the note of Mill in his Greek Testament. The authority for the name "God" is so doubtful that it should not be used as a proof text on the divinity of Christ, and is not necessary, as there are so many undisputed passages on that subject.
Which he hath purchased - The word used here περιεποιήσατο periepoiēsato occurs but in one other place in the New Testament - 1-Timothy 3:13, "For they that have used the office of deacon well, purchase to themselves a good degree and great boldness in the faith." The word properly means "to acquire or gain anything; to make it ours." This may be done by a price, or by labor, etc. The noun (περιποίησις peripoiēsis) derived from this verb is used several times in the New Testament, and denotes "acquisition:" 1-Thessalonians 5:9, God hath appointed us "to obtain" (unto the obtaining or acquisition of) salvation"; 2-Thessalonians 2:14, "Whereunto he called you by our gospel to the obtaining of the glory of our Lord Jesus Christ"; 1-Peter 2:9; Titus 2:14; Ephesians 1:14. In this place it means that Christ had "acquired, gained, or procured," the church for himself by paying his own life as the price. The church is often represented as having thus been bought with a price, 1-Corinthians 6:20; 1-Corinthians 7:23; 2-Peter 2:1.
With his own blood - With the sacrifice of his own life; for blood is often put for life, and to shed the blood is equivalent to faking the life. See the notes on Romans 3:25. The doctrines taught here are:
(1) That the death of Christ was an atoning sacrifice; that he offered himself to purchase a people to his own service.
(2) that the church is, therefore, of special value a value to be estimated by the price paid for it. Compare 1-Peter 1:18-19.
(3) that this fact should make the purity and salvation of the church an object of special solicitude with ministers of the gospel. They should be deeply affected in view of that blood which has been shed for the church; and they should guard and defend it as having been bought with the highest price in the universe. The chief consideration that will make ministers faithful and self-denying is, that the church has been bought with a price. If the Lord Jesus so loved it; if he gave himself for it, they should be willing to deny themselves; to watch, and toil, and pray, that the great object of his death the purity and the salvation of that church - may be obtained.
Made you overseers - Εθετο επισκοπους, Appointed you bishops; for so we translate the original word in most places where it occurs: but overseers, or inspectors, is much more proper, from επι, over, and σκεπτομαι, I look. The persons who examine into the spiritual state of the flock of God, and take care to lead them in and out, and to find them pasture, are termed episcopoi, or superintendents. The office of a bishop is from God; a true pastor only can fulfill this office: it is an office of most awful responsibility; few there are who can fill it; and, of those who occupy this high and awful place, perhaps we may say there are fewer still who discharge the duties of it. There are, however, through the good providence of God, Christian bishops, who, while they are honored by the calling, do credit to the sacred function. And the annals of our Church can boast of at least as many of this class of men, who have served their God and their generation, as of any other order, in the proportion which this order bears to others in the Church of Christ. That bishop and presbyter, or elder, were at this time of the same order, and that the word was indifferently used of both, see noticed on Acts 20:17 (note).
Feed the Church of God - This verse has been the subject of much controversy, particularly in reference to the term Θεου, of God, in this place; and concerning it there is great dissension among the MSS. and versions. Three readings exist in them, in reference to which critics and commentators have been much divided; viz. εκκλησιαν του Θεου, the Church of God; του Κυριου, of the Lord; Κυριου και Θεου, of the Lord and God. From the collections of Wetstein and Griesbach, it appears that but few MSS., and none of them very ancient, have the word Θεου, of God; with these only the Vulgate, and the later Syriac in the text, agree. Κυριου, of the Lord, is the reading of ACDE, several others, the Sahidic, Coptic, later Syriac in the margin, Armenian, Ethiopia, and some of the fathers. Κυριου και Θεου, of the Lord and of God, is the reading of the great majority; though the most ancient are for Κυριου, of the Lord: on this ground Griesbach has admitted this reading into the text, and put Κυριου και Θεου in the margin, as being next in authority.
Mr. Wakefield, who was a professed and conscientious Unitarian, decides for του Θεου, of God, as the true reading; but, instead of translating του ιδιου αἱματος, with his own blood, he translates, by his own Son, and brings some passages from the Greek and Roman writers to show that αἱμα and sanguis are used to signify son, or near relative; and, were this the only place where purchasing with his own blood occurred, we might receive this saying; but, as the redemption of man is, throughout the New Testament, attributed to the sacrificial death of Christ, it is not likely that this very unusual meaning should apply here. At all events, we have here a proof that the Church was purchased by the blood of Christ; and, as to his Godhead, it is sufficiently established in many other places. When we grant that the greater evidence appears to be in favor of του Κυριου, feed the Church of the Lord, which he has purchased with his own blood, we must maintain that, had not this Lord been God, his blood could have been no purchase for the souls of a lost world.
Take heed therefore unto yourselves, and to all the flock, over the which the Holy Ghost hath made you overseers, to (g) feed the church of God, which (h) he hath purchased with (i) his own blood.
(g) To keep it, to feed and govern it.
(h) A notable sentence for Christ's Godhead: which shows plainly in his person, how that by reason of the joining together of the two natures in his own person, that which is proper to one is spoken of the other, being taken as deriving from one another, and not in the original: which in old time the godly fathers termed a communicating or fellowship of properties or attributes, that is to say, a making common of that to two, which belongs but to one.
(i) The words "his own" show forth the excellency of that blood.
Take heed therefore unto yourselves,.... Since the blood of men may be required of those, who are negligent or partial in their office, and shun to declare the whole counsel of God: this exhortation is given them not merely as men, to take care of their bodily health, the outward concerns of life, and provide for themselves and families; nor merely as Christians, but as ministers of the Gospel; that they would take heed to their gifts, to use and improve them, and not neglect them; to their time, that they spend it aright, and not squander it away; and to their spirit, temper, and passions, that they are not governed by them; and to their lives and conversations, that they be exemplary to those who are under their care; and to their doctrine, that it be according to the Scriptures; that it be the doctrine of Christ, and the same with the apostles; that it be according to godliness, and that it tends to edification; that it be sound and incorrupt, pure and unmixed, and all of a piece and consistent with itself; and that they be not infected and carried away with errors and heresies:
and to all the flock; the church and all the members of it, which are compared to a flock of sheep, which are to be looked after and watched over by the ministers of the word, who are as shepherds to them, lest they should be infected, or any damage done them. The people of God are compared to sheep on many accounts; before conversion, for their going astray, when they are as lost sheep; after conversion, for their meek and inoffensive carriage and behaviour, and for their patience in bearing sufferings, to which they are exposed: and a church of Christ is compared to a flock of them, being in Gospel order, folded together and feeding in the same pasture, attending the word and ordinances, under the care of shepherds appointed by Christ the chief shepherd; whose business it is to take heed unto them, and care of them, to learn to know their state and condition, to watch over them, and to feed them with knowledge and with understanding, for which they are qualified by Christ; and they are to take heed unto everyone in the flock, the poor of the flock as well as others, the lambs as well as the sheep, and the sick and the diseased, the torn, and straying, and driven away, as well as the fat and the strong: and this flock, though a little flock, is a holy and beautiful one, a flock of men, and of the souls of men dear to God, to Christ and the blessed Spirit; and a special regard should be had unto them, and that for reasons following:
over which the Holy Ghost hath made you overseers; or "bishops"; this is said to the elders of the church, Acts 20:17 which shows that the office of an elder and a bishop is one and the same office; and this contains in it more than one argument why they should take heed to the flock; as because they are the overseers of it, who have the care and oversight of the flock, that is under their inspection, and is their proper province, and office; and this they were put into by the Holy Ghost, who gave them gifts to qualify them for it, and called, and inclined them to undertake it, as well as moved the people to make choice of them for this purpose; and since, therefore, this was an affair in which the Holy Ghost was so much concerned, it became them very diligently to attend it:
to feed the church of God; with knowledge and understanding; and discharge the whole office of faithful shepherds to the flock, by feeding the flock and not themselves, strengthening the diseased, healing the sick, binding up the broken, bringing again that which was driven away, and seeking up that which was lost: and here is another argument suggested, to stir up to a diligent performance of this work; and that is, that this flock is the church of God, a set of men whom God has chosen for himself, and called by his grace out of the world, and separated for his own use and glory, and among whom he dwells; and therefore to be fed with the faithful word, with the finest of the wheat, and not with the chaff of human schemes, and with the wind of false doctrine, nor with anything that is vain, trifling, and deceitful; but with the solid doctrines of the Gospel, with the words of faith and good doctrine, with the wholesome words of Christ Jesus, which have in them milk for babes and meat for strong men, and with and by the ordinances of the Gospel, which are the green pastures they are to be guided into, and abide in; and in all they are to be directed to Christ, the sum of the word and ordinances, who is the bread of life, and food of faith; and that the church should be thus fed, is the will of Christ, who has appointed and ordered his ministers to feed his lambs and sheep, and has furnished them with what is necessary for this work; this is the design of the ministry of the Gospel, and the administration of ordinances; and the churches of Christ are placed where food may be had, where the word is faithfully preached, and the ordinances truly administered: some copies read, "the church of the Lord"; and others, and so the Complutensian edition, "the church of the Lord and God":
which he hath purchased with his own blood; which being the blood not only of a pure and innocent man, but of one that is truly and properly God as well as man, was a sufficient ransom price to redeem the church and people of God from sin, the law, its curse and condemnation: so that this is no inconsiderable proof of the true and proper deity of Christ; and contains a fresh argument, or reason, why the flock of God and "church of Christ", as the Syriac version reads; or "the church of the Lord and God", as in five of Beza's exemplars: or "of the Lord God", as the Arabic version, should be taken heed unto and fed; because it must needs be dear to God and Christ, and precious to them, since so great a price has been paid for it. The purchaser is God, Christ who is God over all, blessed for ever, not a creature; that could never have made such a purchase, it could not have purchased a single sheep or lamb in this flock, no man can redeem his brother, or give to God a ransom for him, much less the whole flock; but Christ being God, was able to make such a purchase, and he has actually made it, and given a sufficient price for it; not to Satan, with whom these sheep were a prey, and from whom they are taken in virtue of the ransom given; but to God, from whom they strayed, against whom they sinned, and whose law they broke; and this price was not silver and gold, nor men, nor people: but Christ himself, his life and blood; and which were his "own", the human nature, the blood of which was shed, and its life given being in union with his divine person, and was in such sense his own, the property of the Son of God, as the life and blood of no mere man are theirs: and this purchase now being made in this way, and by such means, is a very proper one; it is not made without price, but with an invaluable one; and it is a legal purchase, a valuable consideration being given for it, perfectly equivalent to it; and therefore is a complete one, there is nothing wanting to make it more firm, it is a finished purchase; and it is a very peculiar one, it is a peculiar people that are purchased, called the purchased possession, Ephesians 1:14 and a peculiar price which is paid for it; there is no other of the same kind, nor any thing like it, and it is made by a peculiar person, one that is God and man in one person.
If the Holy Ghost has made ministers overseers of the flock, that is, shepherds, they must be true to their trust. Let them consider their Master's concern for the flock committed to their charge. It is the church He has purchased with his own blood. The blood was his as Man; yet so close is the union between the Divine and human nature, that it is there called the blood of God, for it was the blood of Him who is God. This put such dignity and worth into it, as to ransom believers from all evil, and purchase all good. Paul spake about their souls with affection and concern. They were full of care what would become of them. Paul directs them to look up to God with faith, and commends them to the word of God's grace, not only as the foundation of their hope and the fountain of their joy, but as the rule of their walking. The most advanced Christians are capable of growing, and will find the word of grace help their growth. As those cannot be welcome guests to the holy God who are unsanctified; so heaven would be no heaven to them; but to all who are born again, and on whom the image of God is renewed, it is sure, as almighty power and eternal truth make it so. He recommends himself to them as an example of not caring as to things of the present world; this they would find help forward their comfortable passage through it. It might seem a hard saying, therefore Paul adds to it a saying of their Master's, which he would have them always remember; "It is more blessed to give than to receive:" it seems they were words often used to his disciples. The opinion of the children of this world, is contrary to this; they are afraid of giving, unless in hope of getting. Clear gain, is with them the most blessed thing that can be; but Christ tell us what is more blessed, more excellent. It makes us more like to God, who gives to all, and receives from none; and to the Lord Jesus, who went about doing good. This mind was in Christ Jesus, may it be in us also. It is good for friends, when they part, to part with prayer. Those who exhort and pray for one another, may have many weeping seasons and painful separations, but they will meet before the throne of God, to part no more. It was a comfort to all, that the presence of Christ both went with him and stayed with them.
Take heed . . . unto yourselves--Compare 1-Timothy 3:2-7; 1-Timothy 4:16; 1-Timothy 6:11.
and to all the flock--Compare Hebrews 13:17. Observe here how the personal is put before the pastoral care.
over . . . which the Holy Ghost hath made you--Compare John 20:22-23; Ephesians 4:8, Ephesians 4:11-12; Revelation 3:1. (Acts 14:23 shows that the apostle did not mean to exclude human ordination).
overseers--or, as the same word is everywhere else rendered in our version, "bishops." The English Version has hardly dealt fair in this case with the sacred text, in rendering the word "overseers," whereas it ought here, as in all other places, to have been "bishops," in order that the fact of elders and bishops having been originally and apostolically synonymous, might be apparent to the ordinary English reader, which now it is not [ALFORD]. The distinction between these offices cannot be certainly traced till the second century, nor was it established till late in that century.
to feed the church of God--or, "the Church of the Lord." Which of these two readings of the text is the true one, is a question which has divided the best critics. The evidence of manuscripts preponderates in favor of "THE LORD"; some of the most ancient Versions, though not all, so read; and ATHANASIUS, the great champion of the supreme Divinity of Christ early in the fourth century, says the expression "Church of God" is unknown to the Scriptures. Which reading, then, does the internal evidence favor? As "Church of God" occurs nine times elsewhere in Paul's writings, and "Church of the Lord" nowhere, the probability, it is said, is that he used his wonted phraseology here also. But if he did, it is extremely difficult to see how so many early transcribers should have altered it into the quite unusual phrase, "Church of the Lord"; whereas, if the apostle did use this latter expression, and the historian wrote it so accordingly, it it easy to see how transcribers might, from being so accustomed to the usual phrase, write it "Church of God." On the whole, therefore, we accept the second reading as most probably the true one. But see what follows.
which he hath purchased--"made His own," "acquired."
with his own blood--"His own" is emphatic: "That glorified Lord who from the right hand of power in the heavens is gathering and ruling the Church, and by His Spirit, through human agency, hath set you over it, cannot be indifferent to its welfare in your hands, seeing He hath given for it His own most precious blood, thus making it His own by the dearest of all ties." The transcendent sacredness of the Church of Christ is thus made to rest on the dignity of its Lord and the consequent preciousness of that blood which He shed for it. And as the sacrificial atoning character of Christ's death is here plainly expressed, so His supreme dignity is implied as clearly by the second reading as it is expressed by the first. What a motive to pastoral fidelity is here furnished!
Take heed. Here begin the special admonitions to the elders.
To yourselves. Their own lives must be the first subject of watchfulness. No man can be so exalted that he does not need to watch and pray.
The flock. The church, the fold of the Good Shepherd, of whom they were under-shepherds, or pastors.
To feed the church. "On the sincere milk of the word, that it may grow thereby."
Grievous wolves. The figure of the flock is still kept up. The "grievous wolves" were false teachers, and the special reference is to the Judaizing teachers, who taught that the Gentile Christians must keep the Jewish law. Paul's ministry was a long battle with the schismatics. See 1-Timothy 1:3-4, 1-Timothy 1:20; 2-Timothy 1:15; 2-Timothy 2:17; also John's Third Epistle. By turning to these references the names of some six of these "grievous wolves" will be found. Also in Revelation 2:6 we learn that there were false teachers at Ephesus.
Take heed therefore - I now devolve my care upon you; first to yourselves; then to the flock over which the Holy Ghost hath made you overseers - For no man, or number of men upon earth, can constitute an overseer, bishop, or any other Christian minister. To do this is the peculiar work of the Holy Ghost: to feed the Church of God - That is, the believing, loving, holy children of God; which he hath purchased - How precious is it then in his sight! with his own blood - For it is the blood of the only begotten Son of God, 1-John 1:7.
