..... The belief that the Divine has mixed with the human.’
If we take a close look at the teachings of Christ عليه السلام, we would see that he never directs anyone to this. On the contrary, we witness his teaching to have belief in monotheism (Tawheed) pure from any of the stains of polytheism (Shirk). A very clear proof are the words of Christ related in Mark 12:29: “Listen, O Children of Israel, the Lord God is but a Single Lord.”
May be your perusal of the evidences I have referred to in the previous passages, along with the one I have just shown, will show you whether those evidences taken from the Christians Book support this belief or do they conflict with it and nullify it?
