…no man has either seen Him, or made Him known, but He has revealed Himself. And He has manifested Himself through faith, to which alone it is given to behold God. For God, the Lord and Fashioner of all things, who made all things, and assigned them their several positions, proved Himself not merely a friend of mankind, but also long-suffering in His dealings with them.
Mathetes
Epistle to Diognetus
Chapter VIII
