2 Concerning these things, my beloved, so far as I, in my insignificance, can comprehend, I will instruct you about them, that while we grant to them that He is man, and (while) we at the same time honour Him and call Him God and Lord, yet it is not in any novel fashion, that we have so called Him, nor that we have applied to Him a novel name, which they themselves did not employ. Yet it is a sure thing with us, that Jesus our Lord is God, the Son of God, and the King, the King's Son, Light of light, Creator and Counsellor, and Guide, and the Way, and Redeemer, and Shepherd, Gatherer, and the Door, and the Pearl, and the Lamp; and by many (such) names is He surnamed. But we shall leave aside all (the rest) of them, and prove concerning Him, that He Who came from God is the Son of God, and (is) God.
