Chrislam is the attempt to combine the teachings and practices of Christianity and Islam. As a movement, it began in Nigeria in the 1980s with Shamsuddin Sada, a religious leader who was born a Muslim but became a Christian. He sought to teach the common themes between the two religions. Unfortunately, the movement has been spreading. In Chrislam, both the Bible and the Quran are recognized as inspired holy texts, and during worship services readings from both books are given. One of the premises of Chrislam is the God of Christianity and the God of Islam are the same with different manifestations.

Chrislam is a dangerous theological blending of both Christianity and Islam. It is not logically possible to combine them because they are mutually exclusive. For example, the Bible says that Jesus is the only way, truth, and life (John 14:6), where Islam denies that. The Bible says that Jesus is God in flesh (John 1:1, 14; Colossians 2:9), which is denied by Islam. Christianity says that Jesus was crucified on the cross and rose from the dead three days later, and Islam denies this. Christianity says that salvation is by grace through faith without works (Romans 3:28; 4:1-5; 5:1; Ephesians 2:8-9). Islam denies this. Christianity teaches that God is a Trinity where Islam denies it.

There is no reconciling the differences between Christianity and Islam. Though it's possible for both groups to live in peace (peace which is taught by Christianity), Islam unfortunately is not a religion of peace but of dominance. Since it openly denies the essentials of the Christian faith, and since it also declares that it is the one true religion that must dominate the planet, we as Christians must be very wary of any combination of Christianity and Islam. This is, unfortunately, another deception.
