The quotes clearly show that the truth claims made by Jesus declare the God of the Bible to be unique and cannot be confused with the Muslim Allah, inspite of any ecumenical desire to equate the two. Jesus said "...God must be worship'd in spirit and in truth." Truth. If the worship is not "in truth", then it's a different object of worship.
What is in a name? We use the English word for God "God", not the Greek work "Theos" or the Latin "Deus" or Hebrew "Jehovah". Yet, all these different words refer to the same object, God. In contrast the Mormons refer to god using the same word "god", but it is clear that they are refering to a different object, one who produced a spirit child "Jesus" as well as his spirit brother "Lucifer". In their theology God the father and Jesus are not the same God but different gods.
Muslim's reject that Jesus is God. (John 1) How can Muslims worship God when they deny Him?
Eventually, the Arians lost control of the Church, and Trinitarians declared the Arians to be the apostates.
Since Christians cannot agree to how many books are in the Bible, it's not surprising that they also disagree about the Trinity.
Today, Arians, Unitarians, and several American non-trinitarian sects are a minority among the Christian community.
One more time, I'm not here to defend the quirky theology of religions not in communion with the Roman Catholic Church.
I have posted the official Catholic position, and I stand by it: both Christians and Muslims worship the same God.
If you want to argue theological quirks, you can go to the religion forum on this website. There are plenty of interesting threads there.
