3:2 I have fed you with milk, and not with {b} meat: for hitherto ye were not {c} able [to bear it], neither yet now are ye able.
(b) Substantial meat, or strong meat.
(c) To be fed by me with substantial meat: therefore as the Corinthians grew up in age, so the apostle nourished them by teaching, first with milk, then with strong meat. The difference was only in the manner of teaching.
3:2 I have fed you with milk. When he was at Corinth he treated them as babes, teaching them the simple, rudimentary principles. Milk is metaphorically simple teaching.
And not with meat. Stronger and deeper doctrines. In the school of Christ, like all others, the teaching must be adapted to the advancement of the learner.
3:2 I fed you, as babes, with milk - The first and plainest truths of the gospel. So should every preacher suit his doctrine to his hearers.
3:1-4 The most simple truths of the gospel, as to man's sinfulness and God's mercy, repentance towards God, and faith in our Lord Jesus Christ, stated in the plainest language, suit the people better than deeper mysteries. Men may have much doctrinal knowledge, yet be mere beginners in the life of faith and experience. Contentions and quarrels about religion are sad evidences of carnality. True religion makes men peaceable, not contentious. But it is to be lamented, that many who should walk as Christians, live and act too much like other men. Many professors, and preachers also, show themselves to be yet carnal, by vain-glorious strife, eagerness for dispute, and readiness to despise and speak evil of others.
