In his own words on 1 Timothy

• 1 Timothy 1:17

  He is the only Son of God, our Lord. For he is born One of One, because there is one brightness of light, and there is one word of the understanding. Neither does an incorporeal generation degenerate into the plural number or suffer division. The One who is born is in no way separated from the One who gives life. He is the one and only, the unique. He is as thought is to the mind, as wisdom is to the wise, as a word is to the understanding, as valor is to the brave. As the Father is said by the apostle to be "alone wise," so likewise the Son alone is called wisdom. He is then the "only Son." In glory, everlastingness, virtue, dominion, power, he is what the Father is. Yet all these he has not unoriginately as the Father but from the Father, as the Son, without beginning and equal. Although he is the head of all things, yet the Father is the head of him. For so it is written, "The head of Christ is God."
