Whereunto I am ordained a preacher, and an apostle, (I speak the truth in Christ, and lie not;) a teacher of the Gentiles in faith and verity. I am ordained a preacher - I am set apart, ετεθην, appointed. The word does not imply any imposition of hands by either bishop or presbytery, as is vulgarly supposed.
I speak the truth in Christ - As I have received my commission from him, so I testify his truth. I did not run before I was sent; and I speak nothing but what I have received.
A teacher of the Gentiles - Being specially commissioned to preach the Gospel, not to the Jews, but to the nations of the world.
In faith and verity - Faithfully and truly; preaching the Truth, the whole Truth, and nothing but the Truth; and this fervently, affectionately, and perseveringly.
Instead of εν πιστει, in faith, the Cod. Alexand. has εν πνευματι, in spirit. "A teacher of the Gentiles in spirit and truth."
