And I, brethren, could not speak to you as to spiritual people but as to carnal, as to babes in Christ. 2 I fed you with milk and not with solid food; for until now you were not able to receive it, and even now you are still not able; 3 for you are still carnal. For where there are envy, strife, and divisions among you, are you not carnal and behaving like mere men? 4 For when one says, “I am of Paul,” and another, “I am of Apollos,” are you not carnal? — 1 Corinthians 3:1-4.
The childishness and carnality of the Christians, in following anyone other than Christ, is condemned by Paul. Envy, strife, and divisions are always caused by following a man rather than Christ, impede the spiritual appetite and Christian development, and demonstrate the sinfulness of human nature within.
