Likewise the wives He means the wives both of deacons and of bishops, for they must be aids to their husbands in their office; which cannot be, unless their behavior excel that of others. Let the deacons be Since he mentioned wives, he lays down the same injunction about deacons as he had formerly down about bishops; namely, that each of them -- satisfied within having but one wife -- shall set an example of a chaste and honorable father of a family, and shall keep his children and his whole house under holy discipline. And this refutes the error of those who understand this passage as referring to domestic servants. [1]

Even so must their wives be grave - Chrysostom, Theophylact, Grotius, Bloomfield, and many others, suppose that by the word "wives," here, (γυνᾶικας gunaikas), the apostle means "deaconesses." Clarke supposes that it refers to women in general. The reason assigned for supposing that it does not refer to the wives of deacons, as such, is, that nothing is said of the qualifications of the wives of bishops - a matter of as much importance as that of the character of the wife of a deacon; and that it cannot be supposed that the apostle would specify the one without some allusion to the other. But that the common interpretation, which makes it refer to the wives of deacons, as such, is to be adhered to, seems to me to be clear. Because:
(1) it is the obvious and natural interpretation.
(2) the word here used - "wives" - is never used of itself to denote deaconesses.
(3) if the apostle had meant deaconesses, it would have been easy to express it without ambiguity; compare notes, Romans 16:1.
(4) what is here mentioned is important, whether the same thing is mentioned of bishops or not.
(5) in the qualifications of bishops, the apostle had made a statement respecting his family, which made any specification about the particular members of the family unnecessary. He was to be one who presided in a proper manner over his own house, or who had a well-regulated family; 1-Timothy 3:4-5. By a comparison of this passage, also, with Titus 2:3-4, which bears a strong resemblance to this, it would seem that it was supposed that the deacons would be taken from those who were advanced in life, and that their wives would have some superintendence over the younger females of the church. It was, therefore, especially important that they should be persons whose influence would be known to be decidedly favorable to piety. No one can doubt that the character of a woman may be such, that it is not desirable that her husband should be an officer in the church. A bad woman ought not to be entrusted with any additional power or influence.
Grave - notes, 1-Timothy 3:4.
Not slanderers - compare Titus 2:3, "Not false accusers." The Greek word is διαβόλους diabolous - "devils." It is used here in its original and proper sense, to denote a "calumniator," "slanderer," or "accuser." It occurs in the same sense in 2-Timothy 3:3, and Titus 2:3. Elsewhere in the New Testament, it is uniformly rendered "devil" (compare notes, Matthew 4:1), and is given to Satan, the prince of the fallen angels Matthew 9:34, by way of eminence, as "the accuser;" compare Job 1:6-11 notes, and Revelation 12:10 note. Here it means that they should not be women who were in the habit of calumniating others, or aspersing their character. Mingling as they would with the church, and having an opportunity to claim acquaintance with many, it would be in their power, if they chose, to do great injury to the character of others.
Sober - notes, 1-Timothy 3:2.
Faithful in all things - To their husbands, to their families, to the church, to the Saviour.

Even so must their wives be grave - I believe the apostle does not mean here the wives either of the bishops or deacons in particular, but the Christian women in general. The original is simply: Γυναικας ὡσαυτως σεμνας· Let the women likewise be grave. Whatever is spoken here becomes women in general; but if the apostle had those termed deaconesses in his eye, which is quite possible, the words are peculiarly suitable to them. That there was such an order in the apostolic and primitive Church, and that they were appointed to their office by the imposition of hands, has already been noticed on Romans 16:1 (note). Possibly, therefore, the apostle may have had this order of deaconesses in view, to whom it was as necessary to give counsels and cautions as to the deacons themselves; and to prescribe their qualifications, lest improper persons should insinuate themselves into that office.
Not slanderers - Μη διαβολους· Literally, not devils. See on 1-Timothy 3:7 (note) This may be properly enough translated slanderers, backbiters, tale-bearers, etc., for all these are of their father, the devil, and his lusts they will do. Let all such, with the vast tribe of calumniators and dealers in scandal, remember that the apostle ranks them all with malicious, fallen spirits; a consideration which one would suppose might be sufficient to deter them from their injurious and abominable conduct.
Sober - See on 1-Timothy 3:2 (note)
Faithful in all things - The deaconesses had much to do among the poor, and especially among poor women, in dispensing the bounty of the Church. They were not only faithfully to expend all they had got, and for the purpose for which they got it; but they must do this with impartiality, showing no respect of persons, the degree of distress being the only rule by which the distribution was to be regulated.

(4) Even so [must their] wives [be] grave, not slanderers, sober, faithful in all things.
(4) Regard must also be had for the pastor's and deacon's wives.

Even so must their wives be grave,.... Some instead of "wives" read "women", and understand them of deaconesses, such as were in the primitive churches; whose business it was to visit the poor and sick sisters of the church, and take care of things belonging to them; but it is better to interpret the words of the wives of the deacons, who must be as their husbands, "grave" in speech, gesture, and dress, of an honest report, a good behaviour, and chaste conversation; which will reflect honour and credit to their husbands:
not slanderers; or accusers, and so act like devils, as the word is sometimes rendered; for should they act such a part, and accuse either the poor, or any of the members of the church wrongfully, or on any trifling occasion, as persons addicted to this vice are wont to do, it would be of bad consequence: and they also should be
sober, temperate, not given to wine; excessive drinking is very scandalous in the female sex; and is the rather mentioned here, because women in the eastern countries were too frequently addicted to it:
faithful in all things; as in the marriage bed, so with whatsoever else they are intrusted with in the family, and civil concerns of their husbands; and this is the rather observed, because the wives of deacons may be sometimes intrusted with the church's stock in their husband's absence, to impart to the poor.

their wives--rather, "the women," that is, the deaconesses. For there is no reason that special rules should be laid down as to the wives of the deacons, and not also as to the wives of the bishops or overseers. Moreover, if the wives of the deacons were meant, there seems no reason for the omission of "their" (not in the Greek). Also the Greek for "even so" (the same as for "likewise," 1-Timothy 3:8, and "in like manner," 1-Timothy 2:9), denotes a transition to another class of persons. Further, there were doubtless deaconesses at Ephesus, such as Phœbe was at Cenchrea (Romans 16:1, "servant," Greek, "deaconess"), yet no mention is made of them in this Epistle if not here; whereas, supposing them to be meant here, the third chapter embraces in due proportion all the persons in the service of the Church. Naturally after specifying the qualifications of the deacon, Paul passes to those of the kindred office, the deaconess. "Grave" occurs in the case of both. "Not slanderers" here, answers to "not double-tongued" in the deacons; so "not false accusers" (Titus 2:3). "Sober" here answers to "not given to much wine," in the case of the deacons (1-Timothy 3:8). Thus it appears he requires the same qualifications in female deacons as in deacons, only with such modifications as the difference of sex suggested. PLINY, in his celebrated letter to Trajan, calls them "female ministers."
faithful in all things--of life as well as faith. Trustworthy in respect to the alms committed to them and their other functions, answering to "not greedy of filthy lucre," 1-Timothy 3:8, in the case of the deacons.

Even so must their wives. The word in the Greek may mean women or wives. It is rendered wife in 1-Timothy 3:12. The Revision says, "Women must be, etc." I believe that the Old Version is nearer right. The duties of women generally are not spoken of in the midst of a discussion of elders and deacons. Either deaconesses are meant, or the wives of bishops and deacons; more likely the latter. We know that an injudicious wife may mar the work of a church officer.
Not slanderers. Not given to tattling.

Faithful in all things - Both to God, their husbands, and the poor.
