How then can the Word of God be made, when God by the Word made all things? For if the Word Itself were made, by what other Word was It made? If you say it was the Word of the Word by Which That was made, that Word I call the Only-Begotten Son of God. But if thou dost not call It the Word of the Word1, then grant that that Word was not made, by which all things were made.
