“When I wished at one period to be filled with great quietness, and to shun the path of men, I used to go into a certain field not far from the sea. And when I was near that spot one day, which having reached I purposed to be by myself, a certain old man, by no means contemptible in appearance, exhibiting meek and venerable manners, followed me at a little distance. And when I turned round to him, having halted, I fixed my eyes rather keenly on him. And he said, 'Do you know me?' I replied in the negative. 'Why, then,' said he to me, 'do you so look at me? 'I am astonished,' I said, 'because you have chanced to be in my company in the same place; for I had not expected to see any man here.' […] 'Should any one, then, employ a teacher?' I say, 'or whence may any one be helped, if not even in them there is truth?' 'There existed, long before this time, certain men more ancient than all those who are esteemed philosophers, both righteous and beloved by God, who spoke by the Divine Spirit, and foretold events which would take place, and which are now taking place. They are called prophets. These alone both saw and announced the truth to men, neither reverencing nor fearing any man, not influenced by a desire for glory, but speaking those things alone which they saw and which they heard, being filled with the Holy Spirit. Their writings are still extant, and he who has read them is very much helped in his knowledge of the beginning and end of things, and of those matters which the philosopher ought to know, provided he has believed them. For they did not use demonstration in their treatises, seeing that they were witnesses to the truth above all demonstration, and worthy of belief; and those events which have happened, and those which are happening, compel you to assent to the utterances made by them, although, indeed, they were entitled to credit on account of the miracles which they performed, since they both glorified the Creator, the God and Father of all things, and proclaimed His Son, the Christ [sent] by Him… pray that, above all things, the gates of light may be opened to you; for these things cannot be perceived or understood by all, but only by the man to whom God and His Christ have imparted wisdom.' […] When he had spoken these and many other things, which there is no time for mentioning at present, he went away, bidding me attend to them; and I have not seen him since. But straightway a flame was kindled in my soul; and a love of the prophets, and of those men who are friends of Christ, possessed me; and whilst revolving his words in my mind, I found this philosophy alone to be safe and profitable.”
