But if as a Christian, let him not be ashamed, but let him glorify God in that name.

“Let us then continually persevere in our hope, and the earnest of our righteousness, which is Jesus Christ, "who bore our sins in His own body on the tree," "who did no sin, neither was guile found in His mouth," but endured all things for us, that we might live in Him. Let us then be imitators of His patience; and if we suffer for His name's sake, let us glorify Him. For He has set us this example in Himself, and we have believed that such is the case.”

“Yet if any man suffer as a Christian,.... Because he is one, and professes himself to be one. This name was first given to the disciples at Antioch, either by themselves, or by the Gentiles; however, it being agreeable to them, was retained; it is only mentioned here, and in Act 11:26, let him not be ashamed; neither of Christ, and his Gospel, for which he suffers, nor of the name he bears, nor of the punishment he endures, however ignominious and shameful it may be among men; but let him, as his Lord and master did, endure the cross, and despise the shame, Heb 12:2 but let him glorify God on this behalf: that he bestows this gift upon him to suffer for Christ, as well as to believe in him; and that he does him so much honour to call him to such service, and to strengthen him in it, so as to take it joyfully, and endure it patiently and cheerfully. The Alexandrian copy, and some others, and also the Vulgate Latin, Syriac, and Ethiopic versions, instead of "in this behalf", read "in this name"; that is, of a Christian.”

“Yet if - as a Christian - If he be persecuted because he has embraced the Christian faith, let him not be ashamed, but let him rather glorify God on this very account. Christ suffered by the Jews because he was holy; Christians suffer because they resemble him. The word Χριστιανος, Christian, is used only here and in Act 11:26; Act 26:28. See the note on the Act 11:26 (note).”

“a Christian--the name given in contempt first at Antioch. Act 11:26; Act 26:28; the only three places where the term occurs. At first believers had no distinctive name, but were called among themselves "brethren," Act 6:3; "disciples," Act 6:1; "those of the way," Act 9:2; "saints," Rom 1:7; by the Jews (who denied that Jesus was the CHRIST, and so would never originate the name Christian), in contempt, "Nazarenes." At Antioch, where first idolatrous Gentiles (Cornelius, Act 10:1-2, was not an idolater, but a proselyte) were converted, and wide missionary work began, they could be no longer looked on as a Jewish sect, and so the Gentiles designated them by the new name "Christians." The rise of the new name marked a new epoch in the Church's life, a new stage of its development, namely, its missions to the Gentiles. The idle and witty people of Antioch, we know from heathen writers, were famous for inventing nicknames. The date of this Epistle must have been when this had become the generally recognized designation among Gentiles (it is never applied by Christians to each other, as it was in after ages--an undesigned proof that the New Testament was composed when it professes), and when the name exposed one to reproach and suffering, though not seemingly as yet to systematic persecution. let him not be ashamed--though the world is ashamed of shame. To suffer for one's own faults is no honor (Pe1 4:15; Pe1 2:20), --for Christ, is no shame (Pe1 4:14; Pe1 3:13). but let him glorify God--not merely glory in persecution; Peter might have said as the contrast, "but let him esteem it an honor to himself"; but the honor is to be given to God, who counts him worthy of such an honor, involving exemption from the coming judgments on the ungodly. on this behalf--The oldest manuscripts and Vulgate read, "in this name," that is, in respect of suffering for such a name.”
