2 Corinthians 11:3

Hence Paul speaks against people who are like those I have mentioned, saying: "You have then these promises, beloved; let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God." "For I am jealous for you with a divine jealousy, for I betrothed you to one husband to present a pure virgin to Christ." The Church cannot marry another, having obtained a bridegroom; but each of us individually has the right to marry the woman he wishes according to the law; I mean here first marriage. "I am afraid lest, as the serpent in his craftiness deceived Eve, so also your thoughts may be corrupted from the simplicity which is toward Christ," said the apostle as a very careful and conscientious teacher.

Paul is saying that glory has been given to him not so that he might praise himself but so that he might cast blame on those who, in the name of Christ, were preaching against Christ and by whom the Corinthians were being seduced.

But, to come now to Moses, why, I wonder, did he merely at the time when Joshua was battling against Amalek, pray sitting with hands expanded, when, in circumstances so critical, he ought rather, surely, to have commended his prayer by knees bended, and hands beating his breast, and a face prostrate on the ground; except it was that there, where the name of the Lord Jesus was the theme of speech-destined as He was to enter the lists one day singly against the devil-the figure of the cross was also necessary, (that figure) through which Jesus was to win the victory?

"But I fear lest by any means, as the serpent beguiled Eve through his subtlety, so your minds should be corrupted from the simplicity that is toward Christ." "For although the destruction be yours [alone], yet is the sorrow mine as well." And consider his wisdom. For he does not assert, although they were corrupted; and so he showed when he said, "When your obedience is fulfilled," and "I shall bewail many which have sinned already;" but still he does not leave them to get shameless. And therefore he says, "lest at any time." For this neither condemns nor is silent; for neither course were safe, whether to speak out plainly or to conceal perpetually. Therefore he employs this middle form, saying, "lest at any time." For this is the language neither of one that entirely distrusts, nor entirely relies on them, but of one who stands between these two. In this way then he palliated, but by his mention of that history threw them into an indescribable terror, and cuts them off from all forgiveness. For even although the serpent was malignant, and she senseless, yet did none of these things snatch the woman from punishment. "Beware then," he says, "lest such be your fate, and there be naught to screen you. For he too promising greater things, so deceived." Whence it is plain that these too, by boasting and puffing themselves up, deceived. And he does not say, "Lest by any means as Adam was deceived:" but shows that those men are but women who are thus abused, for it is the part of woman to be deceived. […]

And again Paul saith, "I fear lest, as the serpent led Eve astray in its guile, your mind should be corrupted from the simplicity that is towards Christ;" and here again he teacheth us that whosoever believeth in Christ, it is meet for him to …
