Okay, Joseph, let's take a look at some of what you wrote on your website. From the first page alone it is very clear that you don't understand the Trinity, or you do and are attempting to mislead people as to what it teaches, which is exactly what the Society does. You are no better than the JWs in this regard.
Is the nature of God revealed or concealed by this concept that all three Gods when taken together are really one God?
Nowhere does the doctrine of the Trinity teach that there are three Gods! The Trinity is not tritheism. There is only one God Almighty, the same God of the Old Testament.
The Jehovah's Witnesses continue to imply that Trinitarian Christians worship three Gods, not one; that they are tritheistic, not monotheistic. The Jehovah's Witnesses draw parallels between the Trinity doctrine and triadic pagan worship which they claim is the ultimate source of the Christian Trinity, influenced by Babylonian gods who were worshipped in threes, the Egyptian three-fold gods of Osiris, Isis and Horus, Italian triune godheads, the Trinitarian Hindu group of Brahama, Sira and Visnu, and on and on (Should You Believe, Chapter 5).
But this is false and unfair. The Christian faith is completely monotheistic, and worship is directed to the only one true God Almighty who happens to have a threefold nature: “We do not confess three Gods, but one God in three persons, the “consubstantial Trinity,” (Catholic Catechism, 75). “[T]he Godhead of the Father, Son, and Holy Spirit is one, their glory equal, their majesty coeternal.” Athanasian Creed; DS 75; ND16)” (ibid., 79).
Tritheism, the worship of three Gods at the expense of the unity of God is yet another pitfall which the Trinity doctrine specifically seeks to avoid (Oxford, 1211). And simply because the Jehovah's Witnesses are unable to grasp the meaning of “hypostases” or “Persons” does not entitle them to ascribe to Christians beliefs they do not hold.
More that that are these three persons really only one Being one divine entity?
Your English is tortured. What exactly are you attempting to convey here? The Trinity does not teach that there are three separate divine entities. You should know that.
Why does the Logos that was with God suddenly become the Son, which was only so named later after his birth as a human?
Again, you don't understand the teachings. The Logos doesn't suddenly become the Son, since the Son, the Word, is and always has been eternal. God the Son, (the Word) does not become the Son at birth/incarnation. And the created humanity, the creature Jesus, the man of the God-man equation of the hypostatic union, was not the Almighty. This would make more sense to you if you understood immanent versus economic Trinity. Furthermore, the Word was in fact referred to as Son long before Jesus was born: Psalm 2:7 reads, "I will declare the decree; The Lord has said to me, "You are my Son, Today I have begotten you." This does not refer to the moment of the birth of Jesus on earth. And begotten here does not mean created in the procreative sense.
Should it not say the Father, the Logos, and the Holy Spirit?
But Matthew 28:19 reads "Father, Son and Holy Spirit," all one name, not three. Who are you to change "Son" to "Logos?" You are playing semantic games. And you aren't reading all Scripture relevant to the issues. You are allowing an imagined tail wag the dog.
Does this explanation support the clear Biblical texts that teach us that there is but one BEING who can in the absolute sense be called God?
But that is exactly what the Trinity doctrine teaches; three hypostasis, not three separtate Gods or entities. And Jesus was a divine person who assumed a human nature. Joseph, I'm going to give you the benefit of the doubt that you honestly just don't understand it, but your logic is flawed, and you have not the slightest clue what the doctrine of the Trinity actually teaches. You are no better than the JW Society, and before you begin to mislead others into believing something that isn't true, you need to get a firm grasp on what it teaches first.That is only fair. But you are way in over your head on this one and I caution anyone to be very careful when reading his web site because it is a minefield of distortion.
Learn what the doctrine actually teaches, then criticize, please.
