Joh 1:41 ...We have found the Messiah (which is, being translated, the Christ).
This Jesus claimed to be both Lord and the Messiah (Christ), Christ is not a last name it is a title of divinity.
It is also said of him in Col 1:16 - For all things were created in Him, the things in the heavens, and the things on the earth, the visible and the invisible, whether thrones or dominions or principalities or powers, all things were created through Him and for Him. And in Col 2:9 - For in Him dwells all the fullness of the Godhead bodily.
These are claims that the Muslims will not recognize so why would they even refer to Him???
You may think so, many others would disagree.
