I think nobody denies the Son
I see that you use the modern way of representing body, spirit and soul. The ancient way was to put them, in order of importance, as body, spirit and soul (the soul being the connection with God). Modern reinterpretation puts them as body, soul and spirit.
Just as a curiosity, I would like to say that they are all a simplification from the Bible. In Hebrew, there are 6 terms to represent the human being, not 3. They traduced different words with the same term in order to reach the 3 that we know (body, spirit and soul). Maybe this was done to refer to the trinity, but it is not what the Bible says.
1. Guf (body): the material shell, subject to death
2. Nefesh (lower animal soul): the seat of instincts, passions, urges; it is very connected to the bodily needs and allows the body to stay in a vegetative state
3. Ruach (spirit): one's energy, thought, breath; the seat of the spirit is in the blood, as described in the Bible. The spirit is subject to death.
4. Neshamah (upper soul): this is the divine spark of God in us; this is what makes us men (different from animals); not everybody is aware of it and conducts a life like a soulless animal; only cultivating it properly, one can develop it and bond to God. You can see the Neshamah (which we could define as the innermost strings of a person) in great men, because when it becomes revealed, you always have a sense of a superior things. See Jesus, the geniuses, the people who changed the world. The Neshamah is immortal.
5. Chaya ("living"): this is a sort of higher eternal spirit of existence; it's difficult to define, because most people will never know it.
6. Yekida ("union"): this is the part that is always bonded to God. Here, we are one with God, we don't have an identity ourselves. We will experience this condition of our soul after the final judgment.
Usually, our Bibles translate Nefesh and Neshamah as "soul". Chaya and Yekida are translated in many different ways (but never the right way): spirit, soul, wind, force, etc.
