But I, brethren, could not address you as spiritual men, but as men of the flesh, as babes in Christ. I fed you with milk, not solid food; for you were not ready for it; and even yet you are not ready, for you are still of the flesh. For while there is jealousy and strife among you, are you not of the flesh, and behaving like ordinary men? For when one says, “I belong to Paul,” and another, “I belong to Apol′los,” are you not merely men?
What then is Apol′los? What is Paul? Servants through whom you believed, as the Lord assigned to each. I planted, Apol′los watered, but God gave the growth. So neither he who plants nor he who waters is anything, but only God who gives the growth. He who plants and he who waters are equal, and each shall receive his wages according to his labor. For we are God’s fellow workers; you are God’s field, God’s building.
1 Corinthians 3:1-9 (RSV)
