1 Corinthians 7:6

But this I say by way of concession, not of commandment.

This verse has been grossly misunderstood as a denial of his inspiration on Paul's part, as if he had said that he was in some manner unsure of the advice he gave. This is not true at all; but it indicates that such behavior as celibacy and married couples refraining from cohabitation for "a season" were allowable, but not required, a concession not a commandment. There is no restriction whatever upon Paul's inspiration visible in this verse.
