John Calvin on 1 Corinthians 13:11

11. When I was a child He illustrates what he had said, by a similitude. For there are many things that are suitable to children, which are afterwards done away on arriving at maturity. For example, education is necessary for childhood; it does not comport with mature age. “Elle ne conuient point a ceux qui sont en aage de discretion;” — “It does not become those who are at the age of discretion?’ So long as we live in this world, we require, in some sense, education. We are far from having attained, as yet, the perfection of wisdom. That perfection, therefore, which will be in a manner a maturity of spiritual age, will put an end to education and its accompaniments. In his Epistle to the Ephesians, (Ephesians 4:14,) he exhorts us to be no longer children; but he has there another consideration in view, of which we shall speak when we come to that passage.
