The Enchiridion

I cannot express, my beloved son Laurentius, the delight with which I witness your progress in knowledge, and the earnest desire I have that you should be a wise man: not one of those of whom it is said, “Where is the wise? Where is the scribe? Where is the disputer of this world? Has not God made foolish the wisdom of this world?” but one of those of whom it is said, “The multitude of the wise is the welfare of the world,” and such as the apostles wishes those to become, whom he tells, I would have you wise unto that which is good, and simple concerning evil. Now, just as no one can exist of himself, so no one can be wise of himself, but only by the enlightening influence of Him of whom it is written, All wisdom comes from the Lord.
