Charles Ellicott Commentary 2 Corinthians 6:3

"giving no occasion of stumbling in anything, that our ministration be not blamed;" — 2 Corinthians 6:3 (ASV)

Giving no offence...—The participial construction is resumed from 2 Corinthians 6:1, 2 Corinthians 6:2 being treated as parenthetical. A subtle distinction in the two forms of the Greek negative suggests the thought that he is here giving, as it were, his own estimate of his aim and endeavour in his work. He avoids all occasion of offence, not because he fears censure for himself, but that the ministry be not blamed.
