1 Corinthians 3:1-4

And I, brothers and sisters, could not speak to you as spiritual people, but only as fleshly, as to infants in Christ.

I gave you milk to drink, not solid food; for you were not yet able to consume it. But even now you are not yet able,

for you are still fleshly. For since there is jealousy and strife among you, are you not fleshly, and are you not walking like ordinary people?

For when one person says, “I am with Paul,” and another, “I am with Apollos,” are you not ordinary people?
