Contradiction with Matthew 5:37
This passage emphasizes straightforward communication with honesty, contrasting with any subtlety Paul might use in persuading the Corinthians of his intentions.
Matthew 5:37: But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.
Contradiction with Galatians 4:16
Here, Paul questions if he becomes an enemy by telling the truth, possibly creating tension with any perception of not being forthright in 2 Corinthians 7:3.
Galatians 4:16: Am I therefore become your enemy, because I tell you the truth?
Contradiction with James 5:12
James advises letting "yes" be yes, and "no," no, which may seem at odds with nuanced appeals as shown in 2 Corinthians 7:3.
James 5:12: But above all things, my brethren, swear not, neither by heaven, neither by the earth, neither by any other oath: but let your yea be yea; and [your] nay, nay; lest ye fall into condemnation.
Contradiction with 1 John 3:18
This verse encourages loving not in word or tongue, but in deed and truth, which may conflict with any perceived necessity of Paul to assure the Corinthians in 2 Corinthians 7:3.
1 John 3:18: My little children, let us not love in word, neither in tongue; but in deed and in truth.
