I’m saying that Christians believe God is the Most Holy Trinity, the Triune God.
I think your argument here is becoming quite thin. I would think the response is obvious, but I’ll be brief:
Do practicing Jews hold that Jesus is God?
Do practicing Jews believe the Holy Spirit is God?
Do (orthodox) Christians share their views above?
Therefore, are the two religions view of the One True God the same or different?
Did Old Testament practicing Jews believe in a special Angel of the Lord theophany + THE Messiah to come?
Do practicing Jews believe the Holy Spirit is God?
After reading these verses, what do you think?
* Yet they rebelled and grieved his Holy Spirit. So he turned and became their enemy and he himself fought against them. (Isaiah 63:10)
* Do not cast me from your presence or take your Holy Spirit from me. (Psalm 51:11)
You have to remember that the Pharisees and Teachers of the Law distorted parts of that faith; therefore, a Jewish candidate can either go "liberal" -- like many Jews do today...or they can go "Pharisee" like...legalistic...or they can recover the faith of the One True God of the Old Testament -- one that reveals the Holy Spirit (Is. 63:10; Ps. 51:11) as well as the Messiah.
Bottom-line: TRUE Judaism doesn't discount Isaiah 63:10 and Psalm 51:11. And, as for the Messiah, if somebody thinks He only suddenly appeared on the Jewish scene about 2,000 years ago, may I recommend a few books?
* Christ B.C.: Becoming Closer Friends with the Hidden Christ of the Old Testament by Bill Myers (Regal Books)
* Knowing Jesus Through the Old Testament by Christopher J.H. Wright (InterVarsity Press)
Therefore, are the two religions view of the One True God the same or different?
(Surely by now you've heard the term, Judeo-Christian right???)
