The next point is to investigate as briefly as possible the subject of the Holy Spirit. All who perceive, in whatever manner, the existence of Providence, confess that God, who created and disposed all things, is unbegotten, and recognise Him as the parent of the universe. Now, that to Him belongs a Son, is a statement not made by us only; although it may seem a sufficiently marvellous and incredible assertion to those who have a reputation as philosophers among Greeks and Barbarians, by some of whom, however, an idea of His existence seems to have been entertained, in their acknowledging that all things were created by the word or reason of God.(Book I, Chapter 3, Part 1)

The word or reason of God is the logos, as articulated by Heraclitus, Plato, Aristotle, and practically the entire pantheon of Greek philosophy. It is a concept especially advanced by the Stoics.

Philo of Alexandria, a Hellenized Jewish philosopher writing in the generation before Jesus, offered, "For there are, as it seems, two temples of God; one being this world, in which the High Priest is the Divine Logos, His own first-born son... For God is his Father (who is also Father of all things) and Wisdom is his Mother, through whom the Universe came into being." (De Profugis, 20, Mi, page 562)

The Evangelist John begins his book with, "In the beginning was the Word, and the Word was with God, and the Word was God. He was with God in the beginning. Through him all things were made; without him nothing was made that has been made. In him was life, and that life was the light of men. The light shines in the darkness, but the darkness has not understood it."
