This part clearly and unambiguously affirms that Jesus-Christ was not only the Son of God but actually God Himself. This is expressed by the English formulation “of one essence with the Father” (ὁμοούσιον τῷ Πατρί in Greek with the key term homousios meaning “consubstantial”). This is *THE* core belief of Christianity: that Jesus was the theanthropos, the God-Man or God incarnate. This belief is categorically unacceptable to Islam which says that Christ was a prophet and by essence a ‘normal’ human being.
