This is like asking why is the son, the son?
People seem to get really confused about the tri part concept
Need to remember human being are created in the image of God and when we say “image” we’re not saying we go look physically like God
We say we are created in the image of God it means we are also tripart beings... we are the only living thing on this planet that is of three parts...
If you really want understand the trinity look at yourself as a three-part being and try to understand..... we are a spirit and we have soul and we have a physical manifestation
Precisely. The second person of the trinity is incarnate because he is incarnate. If he were not incarnate he would not be the second person of the trinity.
The Father is incarnate in Christ. The Holy Spirit is incarnate in Christ. Christ is God incarnate.
