1 Corinthians 3:5

(2) Who then is Paul, and who [is] Apollos, but ministers by whom ye believed, even as the Lord gave to every man?

(2) After he has sufficiently reprehended ambitious teachers, and those who foolishly esteemed them, now he shows how the true ministers are to be esteemed, that we do not attribute to them more or less than we ought to do. Therefore he teaches us that they are those by whom we are brought to faith and salvation, but yet as the ministers of God, and such as do nothing of themselves, but God so working by them as it pleases him to furnish them with his gifts. Therefore we do not have to regard or consider what minister it is that speaks, but what is spoken: and we must depend only upon him who speaks by his servants.
