From Augustine's Confessions, Book IV:

When I hear this or that brother Christian, who is ignorant of [scientific] matters and thinks one thing the case when another is correct, with patience I contemplate the man expressing his opinion. I do not see it is any obstacle to him if perhaps he is ignorant of the position and nature of a physical creature, provided that he does not believe something unworthy of you, Lord, the Creator of all things (1 Macc. 1: 24). But it becomes an obstacle if he thinks his view of nature belongs to the very form of orthodox doctrine, and dares obstinately to affirm something he does not understand. But such an infirmity in the cradle of faith is sustained by mother charity, until the new man "grows up into a mature man and is no longer carried about by any wind of doctrine" (Eph. 4: 13).
