For to you Gentiles I speak, etc. He confirms by a strong reason, that nothing shall be lost by the Gentiles, were the Jews to return again to favor with God; for he shows, that the salvation of both is so connected, that it can by the same means be promoted. For he thus addresses the Gentiles, -- "Though I am peculiarly destined to be your Apostle, and ought therefore with special care to seek your salvation, with which I am charged, and to omit as it were all other things, and to labor for that only, I shall yet be faithfully discharging my office, by gaining to Christ any of my own nation; and this will be for the glory of my ministry, and so for your good." [1] For whatever served to render Paul's ministry illustrious, was advantageous to the Gentiles, whose salvation was its object. And here also he uses the verb parazelosai, to provoke to emulation, and for this purpose, that the Gentiles might seek the accomplishment of Moses' prophecy, such as he describes, when they understood that it would be for their benefit.

1 - The meaning attached here to the words ten diakonian mou doxazo, is somewhat different from what is commonly understood. Its classical sense, "highly to estimate," is what is generally given here to the verb: but Calvin takes it in a sense in which it is mostly taken in Scripture, as meaning, "to render illustrious," or eminent, "to render glorious." The construction of the two Romans 11:13 and 14, is somewhat difficult, and the meaning is not very clear. To include the words, "as I am indeed the Apostle of the Gentiles," in a parenthesis, as it is done by some, would render the sense more evident, and to add "this" after "say," and "that" before "I render." The version then would be as follows, -- 13. For I say this to you Gentiles (as I am indeed the Apostle of the Gentiles,) that I render my ministry glorious, 14. If I shall by any means excite to emulation my own flesh and save some of them. The sentiment in the last clause is the same as that at the end of Romans 11:11. The Vulgate, and some of the Latin Fathers, and also Luther, read doxaso in the future tense; which would make the passage read better, -- "that I shall render," etc. These two verses are not necessarily connected with the Apostle's argument; for in the following verse he resumes the subject of Romans 11:12, or rather, as his usual manner is, he states the same thing in other words and in more explicit and stronger terms. So that the gar in the next verse may very properly be rendered "yea," or as an illative, "then." -- Ed.

For I speak to you Gentiles - What I am saying respecting the Jews, I say with reference to you who are Gentiles, to show you in what manner you have been admitted to the privileges of the people of God; to excite your gratitude; to warn you against abusing those mercies. etc. As Paul also was appointed to preach to them, he had a right to speak to them with authority.
I am the apostle of the Gentiles - The apostle of the Gentiles, not because other apostles did not preach to Gentiles, for they all did, except perhaps James; nor because Paul did not himself preach occasionally among the Jews; but because he was especially called to carry the gospel to the Gentiles, and that this was his original commission Acts 9:15; because he was principally employed in collecting and organizing churches in pagan lands; and because the charge of the Gentile churches was especially intrusted to him, while that of the Jewish churches was especially intrusted to Peter; see Galatians 1:16; Ephesians 3:8; Galatians 2:7-8. As Paul was especially appointed to this function, he claimed special authority to address those who were gathered into the Christian church from pagan lands.
I magnify mine office - I honor δοξάζω doxazō my ministry. I esteem it of great importance; and by thus showing that the gospel is to be preached to the Gentiles, that the barrier between them and the Jews is to be broken down, that the gospel may be preached to all people, I show that the office which proclaims this is one of signal honor. A minister may not magnify himself, but he may magnify his office. He may esteem himself as less than the least of all saints, and unworthy to be called a servant of God Ephesians 3:8, yet he may feel that he is an ambassador of Christ, intrusted with a message of salvation, entitled to the respect due to an ambassador, and to the honor which is appropriate to a messenger of God To unite these two things constitutes the dignity of the Christian ministry.

This and the following verse should be read in a parenthesis. St. Paul, as the apostle of the Gentiles, wished to show them the high pitch of glory and blessedness to which they had been called, that they might have a due sense of God's mercy in calling them to such a state of salvation; and that they might be jealous over themselves, lest they should fall as the Jews had done before them: and he dwells particularly on the greatness of those privileges which the Gentiles had now received, that he might stir up the minds of his countrymen to emulation, and might be the means of saving some of them, as he states in the following verse.
I magnify mine office - This is a very improper translation of την διακονιαν μου δοξαζω, which is, literally, I honor this my ministry. Dr. Taylor has justly observed that magnify, except when applied to the most High, carries with it, in our language, the idea of stretching beyond the bounds of truth; whereas the apostle simply means that he does justice to his ministry, by stating the glorious things which he was commissioned to preach among the Gentiles: blessings which the Jews by their obstinacy had forfeited.

(8) For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, (m) I magnify mine office:
(8) He witnesses by his own example, that he goes before all others in this regard.
(m) I make noble and famous.

For I speak to you Gentiles,.... The church at Rome, as the primitive churches for the most part did, consisted of Jews and Gentiles; hence the apostle sometimes addresses the one, as in Romans 2:17, and sometimes the other, as here; and this he does to observe unto them the grace and goodness of God, in enriching them with the Gospel of salvation; and that they might not despise the Jews, from whom it first came out, and through whose fall it came to them, and was preached among them by some of that nation:
in as much as I am the apostle of the Gentiles. He was ordained and set apart by God, in his eternal purposes, to be a teacher of the Gentiles; he was sent immediately by Christ to bear his name among them, though not among them only, to the exclusion of the people of Israel; he chiefly preached the Gospel to them, though sometimes to the Jews also; and the success of his ministry was mostly among the uncircumcision, though he sought by all ways and means to gain both Jews and Gentiles: hence he addresses the Gentiles with greater freedom and boldness, because he was their apostle, and had been so useful among them; and is a reason why we Gentiles should have a special regard to his writings; for though every word of God is pure, and all Scripture is divinely inspired, and is profitable on one account or other; nor is any part of it to be slighted and neglected; yet as Paul's epistles are written chiefly to the Gentile churches, excepting that to the Hebrews, and which some question whether it is his, they ought especially to be attended to by us; though, alas, of all the inspired writings they are had in the least esteem:
I magnify mine office: not himself, for he was not of a self-exalting spirit, but humble and lowly minded, ready at all times to own himself to be less than the least of saints and the chief of sinners; but his office, which he had received from Christ, as an instance of his grace and favour. This was magnified partly by the miracles, signs, and wonders done by him, in proof, and for the confirmation of his apostleship; and partly by his constant, diligent, and faithful preaching of the Gospel: as also by the unwearied pains he took to spread it far and near; and likewise by the numbers of souls he was the means of bringing to the knowledge of Christ; and it was no small accession of glory to his office, as an apostle of the Gentiles, that he was an instrument of the conversion of many among the Jews.

I speak--"am speaking"
to you Gentiles--another proof that this Epistle was addressed to Gentile believers. (See on Romans 1:13).
I magnify--"glorify"
mine office--The clause beginning with "inasmuch" should be read as a parenthesis.

I magnify my office - Far from being ashamed of ministering to the gentiles, I glory therein; the rather, as it may be a means of provoking my brethren to jealousy.
