Thematic Bible: Who is immature

And I, brethren, could not speak unto you as unto spiritual, but as unto carnal, as unto babes in Christ. I fed you with milk, not with meat; for ye were not yet able to bear it : nay, not even now are ye able; for ye are yet carnal: for whereas there is among you jealousy and strife, are ye not carnal, and do ye not walk after the manner of men?

Of whom we have many things to say, and hard of interpretation, seeing ye are become dull of hearing. For when by reason of the time ye ought to be teachers, ye have need again that some one teach you the rudiments of the first principles of the oracles of God; and are become such as have need of milk, and not of solid food. For every one that partaketh of milk is without experience of the word of righteousness; for he is a babe.
