Your response shows patience and a degree of objectivity. I respect that!

What is considered as Arianism is a strong departure from Trinitarianism of present day Christianity. Or from my point of view, Trinitarianism is a strong departure from the teachings of the Son of Mary.
As for the book you call the Bible I would say that there is no definitive copy of this work that can be claimed as the actual word of God. All versions that I know of are third person renderings of what men say that men say that God said or willed. The Second Council of Nicaea assembled a collection of writings that they concluded should be the 'Word of God' and called it the common book or in Latin, Biblios Vulgatus. Current versions of the Bible such as the King James or Jerusalem Bible differ greatly from this original work.
Taking the Bible with it's numerous versions, consistant inconsistencies and obvious problems with natural or scientific phenomena it becomes very hard for any scholarly student with personal integrity to accept this book at face value. This Bible, in essence, is the words of men claiming to report on the history of those supposedly associated with God.
Though claiming to be the word of God, there is no First Person dialog in this book that actually claims to be from God.

Once again, please do not mistake me for someone that does not Believe in God, for I most certainly do. I also believe in the Virgin Birth of the Son of Mariam and that the Son of Mariam was in fact the Massiah to the Children of Israel.
I do not though, call the Son of Mariam the Son of God, not do I view him as co-equal with the God. Remember the first and second commandments of God and then it is easy to understand why I say so.

Thank you for the conversation.
And may God give us all guidance to the truth.
