This is the trinity:
The epitome of the discourse is that the Reality of Christ was a clear mirror, and the Sun of Reality—that is to say, the Essence of Oneness, with its infinite perfections and attributes—became visible in the mirror. The meaning is not that the Sun, which is the Essence of the Divinity, became divided and multiplied—for the Sun is one—but it appeared in the mirror. This is why Christ said, “The Father is in the Son,” meaning that the Sun is visible and manifest in this mirror.
Yes that is the Baha'i explanation, it is not the Trinity many Christians will accept. Your heart has, well done to you. There are further aspects of this that are in my current vision.
In christianity, this italic is expressed by jesus being a physical "image" of an invisible god. Again, christians use Is because they see no differientation between the father and son. (They are one; unified)
It is the Man Jesus that is the Mirror. This is what I think you are yet to consider and it will be the point that will be made in the next few passages.
Also In this regard all the Great Beings are the Mirror. We can put any Name on the mirror, it is God that gave us that Name and that person.
Its an expression of unity between two people: the sun is the rays. They cannot be separated and still call them rays.
Now the crucial part of this explanation, Yes you are correct, the Sun and the Rays can not be seperated, this leads us to the next part;
What trinity are you refereing to where scripture says jesus the human is god the spirit?
This is the key, it is not the Human Jesus but the 'Christ' which is reflected in the Mirror of Jesus, that is the Holy Spirit of God, Christ is the Rays of the Sun. Christ is the Rays that comes from all the Great Beings, the Mirrors. This is how Jesus is the First and the Last.
Each time God sends a Mesenger, a Great Being, they are born as 'Christ', of the Holy Spirit.
Which denomination rejects the father for the son?
All do. The Father in many Passages is not God, it is another Name or Station.
The Father is Baha'u'llah. Christ in the Station of the Son has come back in the Station of the Father, a Natural progression this world offers, a Son over time becomes a Father.
Do you understand the nature between father and manifestation?
The Father is a Title given to Baha'u'llah, the Manifestation of God for this age.
The Father is not God, the Father is also Christ, Christ is also the Son and the Stations of all the Great Beings. A spiritual relationship is inferred in the station of Prophethood. Thus, Abraham was the "Friend" of God, Moses was His "Lawgiver",
Jesus was the (spiritual) "Son" of God, Muhammad was the "Apostle" of God, The Bab was the "Gate" of God.and Baha'u'llah is the "Glory" of God.
