And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, even as unto babes in Christ.
All Commentaries on 1 Corinthians 3:1 Go To 1 Corinthians 3
Ambrosiaster
AD 400
These people were carnal because they were still slaves to the desires of the present age. Although they had been baptized and had received the Holy Spirit, they were carnal because after their baptism they had returned to their old lives, which they had renounced. The Holy Spirit dwells in a person into whom he has poured himself if that person stays firm in the conviction of his new birth. Otherwise he departs, but only provisionally. If that person repents, the Spirit will return, for he is always ready for what is good, being a lover of repentance. Commentary on Paul’s Epistles.
