“Now, then, suppose we advise all our brethren not to teach their children any of these things, because on the outpourings of the Holy Spirit the apostles immediately began to speak the language of every race; and warn every one who has not had a like experience that he need not consider himself a Christian, or may at least doubt whether he has yet received the Holy Spirit? No, no; rather let us put away false pride and learn whatever can be learnt from man; and let him who teaches another communicate what he has himself received without arrogance and without jealousy. . . . Moreover, love itself, which binds men together in the bond of unity, would have no means of pouring soul into soul, and, as it were, mingling them one with another, if men never learnt anything from their fellow-men” (Augustine, On Christian Doctrine, 520).
