At the risk of being flamed None of these religons share the same God.I am not sure all Christian sects share the same God .
All three faiths do share geographical cultural and textual elements.

Not a flame...maybe a slow roast, like coffee... :)

You've got a burden of proof here that you haven't met.

I can go to a Lutheran, Methodist, Presbyterian, Baptist, Roman Catholic, et. al., and pick up roughly the same Bible and read about the same triune God. The translations vary, but that's because we aren't fluent in Hebrew and Greek. :) Granted, there are indeed procedural differences, i.e. where in the church women can serve, what constitutes Holy Communion, etc, but that doesn't change that all Christians believe that, having seen the divine law that we are supposed to live by, have fallen short, and need to ask God through his Son, Jesus Christ, for forgiveness of our sins, so that we may enter Heaven.

• ...for all have sinned and fall short of the glory of God, --Romans 3:23
• Jesus answered, "I am the way and the truth and the life. No one comes to the Father except through me. --John 14:6

Among said denominations are also common creeds that point out significant, undisputed events that Christians believe. Such an example is the Apostle's Creed, which I've personally recited in Lutheran and Catholic churches.

Given these commonalities it would to seem to me quite difficult to argue that Christian denominations worship different Gods.

I contend that the three major Faiths originating in the near East do not worship the same God
As for Christians I was more tentative but there is much more difference betwen say........ Mormon and Cathoic and Pentecostal theology to settle this question so easily

Such an example is the Apostle's Creed, which I've personally recited in Lutheran and Catholic churches.

As a Lutheran, I would point out that Lutherans refer to the Holy Christian Church, not the Holy Catholic Church. A minor but significant difference. Other denominations may go either way, and may have other minor differences.

You are right about the triune God. This is the basis for Christianity. If one (or ones congregation) does not believe this, he is not Christian; No matter what he may call himself.
