Origen of Alexandria : But he who is on the white horse is called "faithful," not so much because he trusts as because he is trustworthy, that is, he is worthy of being trusted. According to Moses, the Lord is faithful and true. For he is also true in contradistinction to a shadow and a type and an image, since the Word that powers from heaven is true. For the Word on earth is not like the Word in heaven, inasmuch as he has become flesh and is expressed by means of a shadow and types and images. — COMMENTARY ON THE GOSPEL OF John 2.49
