as newborn babes, long for the pure milk of the Word, that you may grow thereby,
Paul reproves the Corinthians because they were like children, and therefore they could not take strong food, but were fed with milk. (1 Corinthians 3:1.) Almost the same words are found in Hebrews 5:12. But in these passages those are compared to children who remain always novices and ignorant scholars in the doctrine of religion, who continued in the first elements, and never penetrated into the higher knowledge of God. Milk is called the simpler mode of teaching, and one suitable to children, when there is no progress made beyond the first rudiments. Justly, then, does Paul charge this as a fault, as well as the author of the Epistle to the Hebrews. But milk, here, is not elementary doctrine, which one perpetually learns; and never comes to the knowledge of the truth, but a mode of living which has the savor of the new birth, when we surrender ourselves to be brought up by God. In the same manner infancy is not set in opposition to manhood, or full age in Christ, as Paul calls it in Ephesians 4:13, but to the ancientness of the flesh and of former life. Moreover, as the infancy of the new life is perpetual, so Peter recommends milk as a perpetual aliment, for he would have those nourished by it to grow.
