(31) Why did the angel say to her, “I will multiply thy seed, and it shall not be numbered for multitude?” (#Ge 16:9). It is the honour of the docile mind not to be presumptuous or rebellious on account of its progress in knowledge, or because of the very useful seed which it has received from various kinds of erudition; for it does not any more, as wordcatchers and cavillers do, employ all the arguments of encyclical learning to establish any whimsical object, but to prove the truth which is contained in them. And when it has begun to prosecute that by diligent investigation, it is then rendered worthy to behold the sight of its mistress, free from all acceptance of persons, and from all reproof.
