To my mind, it does not seem inconsistent with the teachings of Christ to lead the young to a knowledge of God through sensible objects. When the beautiful structure of the whole world is placed before their eyes, each created object points, as with a finger, to the mutability and the destructibility of all existing things; whereas he who so firmly established and harmoniously united these numberless things must be eternal and immutable. To this it should be added that he who so wisely and skillfully arranged all things ought, in no wise, to be mistrusted or supposed to forget his works or to fail to guide them all in harmony; for among men, a father would be regarded as wicked, if he did not diligently care for his household.
