Brother, thats Trias, which someone has translated as "Trinity" and its not a coeternal God, son and the holy spirit there, its just three, God, his word, and his all knowing nature or wisdom of God. You really didnt have to cut and paste that because I have already stated this exact same thing.
I wanted folks to see the original quote, that's why I posted it.
You don't mind people reading Theophilus as referencing the Trinity, so I don't see a point to discussing the point further.
The point more relevant to the OP is that, whoever uttered the word first, the concept developed over time from strains of thought that can be seen in the Bible depending on interpretation.
