1 Corinthians 3:1-3

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?
