Your post regarding the trinity totally misses the point regarding the true "Christian" doctrine, or Biblical doctrine. You have brought up many historical doctrines, unrelated to the actual and factual statements of The God of the Bible. Don't confuse rogue Christian and cultish doctrines, with true Christianity.
The truly AMAZING thing, is the MISTAKE the Quran made about the Biblical picture of the Trinity. NO WHERE DOES THE BIBLE IMPLY MARY AS PART OF THE TRINITY. YET ACCORDING TO THE QURAN, MARY IS INCLUDED IN IT.....HOW IS THAT????? HOW DID ALLAH ERROR IN SUCH A WAY? I submit to you Allah did not error, but the false prophet that proclaims any scripture but the Bible.
But one of many errors in the Quran.
