Irenaeus : With regard to those (the Marcionites) who allege that Paul alone knew the truth, and that to him the mystery was manifested by revelation, let Paul himself convict them, when he says, that one and the same God wrought in Peter for the apostolate of the circumcision, and in himself for the Gentiles. Peter, therefore, was an apostle of that very God whose was also Paul; and Him whom Peter preached as God among those of the circumcision, and likewise the Son of God, did Paul [declare] also among the Gentiles. For our Lord never came to save Paul alone, nor is God so limited in means, that He should have but one apostle who knew the dispensation of His Son. And again, when Paul says, "How beautiful are the feet of those bringing glad tidings of good things, and preaching the Gospel of peace," he shows clearly that it was not merely one, but there were many who used to preach the truth. And again, in the Epistle to the Corinthians, when he had recounted all those who had seen God after the resurrection, he says in continuation, "But whether it were I or they, so we preach, and so ye believed," acknowledging as one and the same, the preaching of all those who saw God after the resurrection from the dead. — Against Heresies Book III John Chrysostom : But wherefore did he utter at all that same lofty expression, "I labored more abundantly than they?" He saw that the occasion compelled him. For had he not said this, had he only depreciated himself, how could he with boldness call himself to witness, and number himself with the rest, and say, "Whether then it be I or they, so we preach." For the witness ought to be trustworthy, and a great man. But how he "labored more abundantly than they," he indicated above, saying, "Have we no right to eat and to drink, as also the other Apostles?" And again, "to them that are without law as without law." Thus, both where exactness was to be displayed, he overshot all: and where there was need to condescend, he displayed again the same great superiority. But some cite his being sent to the Gentiles and his overrunning the larger part of the world. Whence it is evident that he enjoyed more grace. For if he labored more, the grace was also more: but he enjoyed more grace, because he displayed also more diligence. Seest thou how by those particulars whereby he contends and strives to throw into shade the things concerning himself, he is shown to be first of all? — Homily on 1 Corinthians 38 John Chrysostom : Having exalted the Apostles and abased himself, then again having exalted himself above them that he might make out an equality: (for he did effect an equality, when he showed that he had advantages over them as well as they over him,) and having thereby proved himself worthy of credit; neither so doth he dismiss them, but again ranks himself with them, pointing out their concord in Christ. Nevertheless he doth it not so as that he should seem to have been tacked on to them, but as himself also to appear in the same rank. For so it was profitable for the Gospel. Wherefore also he was equally earnest, on the one hand, that he might not seem to overlook them; on the other, that he might not be on account of the honor paid to them held cheap by those that were under his authority. Therefore he also now makes himself equal again, saying, "Whether then it be I or they, so we preach." "From whomsoever," saith he, "ye choose to learn, learn; there is no difference between us." And he said not, "if ye will not believe me, believe them;" but while he makes himself worthy of credit and saith that he is of himself sufficient, he affirms the same also of them by themselves. For the difference of persons took no effect, their authority being equal. And in the Epistle to the Galatians he doth this, taking them with him, not as also standing in need of them, but saying indeed that even himself was sufficient: "For they who were of repute imparted nothing to me:" nevertheless, even so I follow after agreement with them. "For they gave unto me," saith he, "their right hands." For if the credit of Paul were always to depend on others and to be confirmed by testimony from others, the disciples would hence have received infinite injury. It is not therefore to exalt himself that he doeth this, but fearing for the Gospel. Wherefore also he here saith, making himself equal, "Whether it be I or they, so we preach." Well did he say, "we preach," indicating his great boldness of speech. For we speak not secretly, nor in a corner, but we utter a voice clearer than a trumpet. And he said not, "we preached," but, "even now 'so we preach.'" "And so ye believed." Here he said not, "ye believe," but, "ye believed." Because they were shaken in mind, therefore he ran back to the former times, and proceeds to add the witness from themselves. — Homily on 1 Corinthians 39 Tertullian : To be sure, an amender of that Gospel, which had been all topsy-turvy from the days of Tiberius to those of Antoninus, first presented himself in Marcion alone-so long looked for by Christ, who was all along regretting that he had been in so great a hurry to send out his apostles without the support of Marcion! But for all that, heresy, which is for ever mending the Gospels, and corrupting them in the act, is an affair of man's audacity, not of God's authority; and if Marcion be even a disciple, he is yet not "above his master; " if Marcion be an apostle, still as Paul says, "Whether it be I or they, so we preach; " if Marcion be a prophet, even "the spirits of the prophets will be subject to the prophets," for they are not the authors of confusion, but of peace; or if Marcion be actually an angel, he must rather be designated "as anathema than as a preacher of the gospel," because it is a strange gospel which he has preached. — Against Marcion Book IV Tertullian : I am content with the fact that, between apostles, there is a common agreement in rules of faith and of discipline. For, "Whether (it be) I," says (Paul), "or they, thus we preach." Accordingly, it is material to the interest of the whole sacrament to believe nothing conceded by John, which has been taffy refused by Paul. — On Modesty
