A. 1 Would to God ye could bear with me a little in my folly: and indeed bear with me.
B. 2 For I am jealous over you with godly jealousy:for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
C. 3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.
B’. 4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
A’. 5 For I suppose I was not a whit behind the very chiefest apostles. 6 But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.
Note: this pattern is one of contrasts. Paul speaks “foolishly” (A) by defending his status (A’). B and B’ contrast the true with the counterfeit Jesus. The centre is the warning against being seduced by false teachers.
