Yet if any man suffer as a Christian After having forbidden the Christians to do any hurt or harm, lest for their evil deeds, like the unbelieving, they should become hateful to the world, he now bids them to give thanks to God, if they suffered persecutions for the name of Christ. And truly it is no common kindness from God, that he calls us, freed and exempted from the common punishment of our sins, to so honorable a warfare as to undergo for the testimony of his Gospel either exiles, or prisons, or reproaches, or even death itself. Then he intimates that those are ungrateful to God, who clamor or murmur on account of persecutions, as though they were unworthily dealt with, since on the contrary they ought to regard it as gain and to acknowledge God's favor. But when he says, as a Christian, he regards not so much the name as the cause. It is certain that the adversaries of Christ omitted nothing in order to degrade the Gospel. Therefore, whatever reproachful words they made use of, it was enough for the faithful, that they suffered for nothing else but for the defense of the Gospel. On this behalf, or, In this respect. For since all afflictions derive their origin from sin, this thought ought to occur to the godly, "I am indeed worthy to be visited by the Lord with this and even with greater punishment for my sins; but now he would have me to suffer for righteousness, as though I were innocent." For how much soever the saints may acknowledge their own faults, yet as in persecutions they regard a different end, such as the Lord sets before them, they feel that their guilt is blotted out and abolished before God. On this behalf, then, they have reason to glorify God.

Yet if any man suffer as a Christian - Because he is a Christian; if he is persecuted on account of his religion. This was often done, and they had reason to expect that it might occur in their own case. Compare the notes at 1-Peter 3:17. On the import of the word Christian, and the reasons why the name was given to the disciples of the Lord Jesus, see the notes at Acts 11:26.
Let him not be ashamed -
(1) Ashamed of religion so as to refuse to suffer on account of it.
(2) ashamed that he is despised and maltreated.
He is to regard his religion as every way honorable, and all that fairly results from it in time and eternity as in every respect desirable. He is not to be ashamed to be called a Christian; he is not to be ashamed of the doctrines taught by his religion; he is not to be ashamed of the Saviour whom he professes to love; he is not to be ashamed of the society and fellowship of those who are true Christians, poor and despised though they may be; he is not to be ashamed to perform any of the duties demanded by his religion; he is not to be ashamed to have his name cast out, and himself subjected to reproach and scorn. A man should be ashamed only of that which is wrong. He should glory in that which is right, whatever may be the consequences to himself. Christians now, though not subjected to open persecution, are frequently reproached by the world on account of their religion; and though the rack may not be employed, and the fires of martyrdom are not enkindled, yet it is often true that one who is a believer is called to "suffer as a Christian." He may be reviled and despised. His views may be regarded as bigoted, narrow, severe. Opprobrious epithets, on account of his opinions, may be applied to him. His former friends and companions may leave him because he has become a Christian. A wicked father, or a frivilous and worldly mother, may oppose a child, or a husband may revile a wife, on account of their religion. In all these cases, the same spirit essentially is required which was enjoined on the early Christian martyrs. We are never to be ashamed of our religion, whatever results may follow from our attachment to it. Compare the notes at Romans 1:16.
But let him glorify God on this behalf - Let him praise God that he is deemed not unworthy to suffer in such a cause. It is a matter of thankfulness:
(1) that they may have this evidence that they are true Christians;
(2) that they may desire the advantages which may result from suffering as Christ did, and in his cause. See the notes at Acts 5:41, where the sentiment here expressed is fully illustrated. Compare the Philippians 3:10 note; Colossians 1:24 note.

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 Acts 11:26; Acts 26:28. See the note on the Acts 11:26 (note).

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 Acts 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, Hebrews 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.

a Christian--the name given in contempt first at Antioch. Acts 11:26; Acts 26:28; the only three places where the term occurs. At first believers had no distinctive name, but were called among themselves "brethren," Acts 6:3; "disciples," Acts 6:1; "those of the way," Acts 9:2; "saints," Romans 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, Acts 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 (1-Peter 4:15; 1-Peter 2:20), --for Christ, is no shame (1-Peter 4:14; 1-Peter 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.

Let him glorify God - Who giveth him the honour so to suffer, and so great a reward for suffering.
