Thematic Bible: Who is immature

And I, brothers, could not speak to you as to spiritual, but as to carnal, as to the childlike in Christ. I gave you milk to drink and not solid food, for ye were not yet able. But not even yet are ye able, for ye are still carnal. For whereas among you is envy and strife and divisions, are ye not carnal and walk according to man?

About whom, much subject matter from us is also difficult to explain, since ye have become sluggish in hearing. For also men who ought to be teachers because of the time, ye have need again for some man to teach you the rudiments of the beginning of the oracles of God, and have become men who have need of milk, and not of solid food. For every man partaking of milk is unskilled in the word of righteousness, for he is childlike.
