Muslims believe that 'Isa Ibn Maryam, peace be upon him, was a humble servant of Allah, the Messiah, and one of His prophets and messengers. This is confirmed by the Qur'an who explicitly denies the notions of trinity and incarnation present in mainstream Christian doctrine.
The Qur'an says: "Indeed they have disbelieved those who say:- Allah is the Messiah son of Maryam-" (5:72) and "Indeed they have disbelieved those who say:- Allah is the third of the three-" (5:73). In fact "the Messiah son of Maryam was only a Messenger" (5:75).
Mainstream Christianity believe that Allah was incarnated in a human being, 'Isa Ibn Maryam, who they think to be "God made flesh" but such notion is not only rejected by the Qur'an and Muslims, it also cannot be proven by the Scriptures themselves as no "Gospel of Jesus" reached us in its original form.
With prayers for your success.
