John Chrysostom
So that you might not think the preceding words were spoken in anger, or said by exaggeration, or somehow escaped him involuntarily, he repeats them again. For if someone says something while stirred by anger, he soon repents of his words. But the man who says the same thing a second time shows that he spoke after reflection. He had first resolved it in his mind, and then uttered the words exactly as he had resolved. When Abraham was entreated by the rich man to send Lazarus, he said, "They have Moses and the prophets. If they do not hear them, neither will they hear one risen from the dead" (Lk 16:29, 31). Christ, presenting Abraham as saying this, wishes to show that He wants Scripture to be believed more than those who rise from the dead.

And Paul, when I say Paul I mean Christ together with him, since He Himself acted in Paul's soul, prefers Scripture even to angels descending from heaven. This is entirely just. For although the angels are great, they are servants and ministers. But all Scripture has been sent down to us, written not by servants, but by the Master and God of all. Therefore he says, "If anyone preaches to you a gospel contrary to what we preached to you." He did not say, "this person or that person," which is very wise and not burdensome. Indeed, why would one who possessed such superiority need to mention names, when he embraced all, both those above and those below? By pronouncing a curse upon evangelists and angels, he embraced every dignity. By pronouncing a curse even upon himself, he embraced every tie of kinship and friendship. "Do not tell me," he says, "that your fellow-apostles and friends preach this. I would not spare even myself if I preached what is contrary." Yet he says this not to condemn the other apostles, as though they corrupted the evangelical preaching. No, he says, "whether it was I or they, so we preach" (1 Cor 15:11). He wished only to show that the dignity of persons is not taken into account when truth is at stake. The divine Chrysostom, interpreting the words, "If anyone preaches to you beyond what you received, let him be anathema" (Gal 1:9), says this: "He did not say, if they announced to you something contrary, or completely distorted it. Rather, if they preached even something small besides what you received, or perhaps changed anything, let them be anathema." This interpretation of Chrysostom also concerns Gal 1:8, according to St. Mark of Ephesus in the Confession of the Right Faith.
