Many considerations, young men, prompt me to recommend to you the principles which I deem most desirable, and which I believe will be of use to you if you will adopt them. For my time of life, my many-sided training, yea, my adequate experience in those vicissitudes of life which teach their lessons at every turn, have so familiarized me with human affairs, that I am able to map out the safest course for those just starting upon their careers. By nature’s common bond I stand in the same relationship to you as your parents, so that I am no whit behind them in my concern for you. Indeed, if I do not misinterpret your feelings, you no longer crave your parents when you come to me. Now if you should receive my words with gladness, you would be in the second class of those who, according to Hesiod, merit praise; if not, I should say nothing disparaging, but no doubt you yourselves would remember the passage in which that poet says: ‘He is best who, of himself, recognizes what is his duty, and he also is good who follows the course marked out by others, but he who does neither of these things is of no use under the sun,’
Do not be surprised if to you, who go to school every day, and who, through their writings, associate with the learned men of old, I say that out of my own experience I have evolved something more useful. Now this is my counsel, that you should not unqualifiedly give over your minds to these men, as a ship is surrendered to the rudder, to follow whither they list, but that, while receiving whatever of value they have to offer, you yet recognize what it is wise to ignore. Accordingly, from this point on I shall take up and discuss the pagan writings, and how we are to discriminate among them.

So he is going to offer us criteria by which to judge the writings of the pagans; he wants the young men to make proper use of them.
He is qualified by training and experience . . . and proper concern. He is an exemplary Bishop.
