Why should the nature of God be something simple? Even God from the perspective of the absolute unity has many philosophical implications. Why don't you read Plato Parmenides, the dialoge on The One. You will see the existence of The One isn't as d
simple as you thought. But you could protest and say it is simple, I understand it through my living faith. Well any Christian could tell you the same.
Stopping Christians worshipping God isn't the same as stopping someone with a knife running at someone.
The rest of your docternal confusion can be easily dispersed with this passage from John, Jesus closest disciple.
--------------------
In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.
5 And the light shineth in darkness; and the darkness comprehended it not.
6 There was a man sent from God, whose name was John.
7 The same came for a witness, to bear witness of the Light, that all men through him might believe.
8 He was not that Light, but was sent to bear witness of that Light.
9 That was the true Light, which lighteth every man that cometh into the world.
10 He was in the world, and the world was made by him, and the world knew him not.
11 He came unto his own, and his own received him not.
12 But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
13 Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God.
14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
