No, the God of Islam is not the same as the God of Christianity. In Christianity God is a Trinity, but in Islam God is not a Trinity. It is not possible to have God be a Trinity and also not a Trinity at the same time. Furthermore, because Islam denies the Trinity (that there is one God who is comprised of three distinct persons: Father, Son, and Holy Spirit), it means that Jesus is not the incarnation of the second person of the Trinity.
- Quran, 5:73 (Yusuf Ali), “They do blaspheme who say: Allah is one of three in a Trinity: for there is no god except One Allah. If they desist not from their word (of blasphemy), verily a grievous penalty will befall the blasphemers among them.”
So it is clear that the Quran clearly denies one of the essential Christian doctrines about God’s nature. The God of Islam and the God of Christianity are not the same.
Also, in Islam Jesus is not God in flesh (Surah 4:172, 5:73, 9:30) where in Christianity He is (John 1:1, 14, Col. 2:9). In Christianity Jesus was crucified, but in Islam He was not (Surah 4:158). This is another irreconcilable difference between Islam and Christianity regarding God and who Christ is. In addition, Islam says that the Helper (paraclete in Greek) is Muhammed where the Bible says that the Helper is the Holy Spirit (John 14:26). So, the God of Islam and the God of Christianity are not the same.
However, we also need to point out a gross error on the part of Roman Catholicism regarding this issue. The Catechism of the Catholic Church says in paragraph 841, “The Church's relationship with the Muslims. 'The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind's judge on the last day.'" The Roman Catholic church is wrong. Muslims and Christians do not worship the same God.
