Who, being in the form of God, thought it not a thing to be grasped to be equal with God:
All Commentaries on Philippians 2:6 Go To Philippians 2
Gaius Marius Victorinus
AD 400
What does this mean—“being equal to God”? It means that he [the Son] is of the very same power and substance [as the Father]. … It is in this sense therefore that Christ was equal to God. Note that Paul did not say Christ was “similar to God,” for that would imply that Christ possessed some accidental likeness to the substance of God but not that he was substantially equal. … Thus Christ is the form of God. The form of God is the substance of God. The form and image of God is the Word. The Word is forever with God. The Word is of one substance with the Father, with whom from the beginning it remains forever the Word.
