Do not however think that the Faith is depreciated by being called elementary: for it is indeed the whole power: for when he says, “For every one that useth milk is unskilled in the word of righteousness, for he is a babe” ( c. v. 13 ), it is not this which he calls “milk.” But to be still doubting about these things is [a sign] of a mind feeble, and needing many discourses. For these are the wholesome doctrines. For we call him “a perfect man” [i.e. “of full age”] who with the faith has a right life; but if any one have faith, yet does evil, and is in doubt concerning [the faith] itself, and brings disgrace on the doctrine, him we shall with reason call “a babe,” in that he has gone back again to the beginning. So that even if we have been ten thousand years in the faith, yet are not firm in it, we are babes; when we show a life not in conformity with it; when we are still laying a foundation.
