What are the factors that widen the gap between Muslims and Christians?

The difference between Muslims and Christians is vast due to doctrinal disagreements, and rapprochement is impossible unless Christians abandon their disbelief and embrace Islam. The most prominent deviations of Christians are:

1. Their belief that Christ is the Son of God, a god, and a hypostasis of the Holy Trinity, and that divinity became incarnate in humanity. 2. Their belief in the crucifixion of Christ and his death as a sacrifice for humanity and an atonement for inherited sin. 3. Their stance of support and loyalty to the Jews, who denied Jesus and accused Mary, and their animosity towards Muslims. 4. Their alteration of the Gospel, both in wording and meaning. 5. Their doctrine of salvation, that God sent His only begotten Son to save people from Adam's sin. 6. Their disbelief in the prophethood of Muhammad (peace be upon him), despite it being mentioned in their books. 7. Their belief in the authenticity of the distorted Torah, which attributes imperfections to God and the prophets and ascribes heinous acts to them.
