Get with the times, to used this sad and pathetic line that Body, soul and spirit supports a trinity, is totally fairy land nonsense and pure desperation, grasping at straws.
Jesus quotes the OT -> Hear, Israel: Yehowah our God is one Yehowah. He defines this one, the Father, independently of himself as the Only True God when he was here John 17:3 = you cannot get it any clearer than that, and there are many more verses.
The image aspect, could simply be in God's ways, as it gets elaborated on, explained, with the words, in our likeness. Hence Jesus became the express image of the Father person, when he expressed out the Fathers words Heb 1:3 KJV.
