Chrislam is an attempt to syncretize Christianity with Islam. While it began in Nigeria in the 1980s, Chrislamic ideas have spread throughout much of the world. The essential concept of Chrislam is that Christianity and Islam are compatible, that one can be a Christian and a Muslim at the same time. Chrislam is not an actual religion of its own, but a blurring of the differences and distinctions between Christianity and Islam.
Advocates of Chrislam point to facts such as Jesus being mentioned 25 times in the Qur’an, or Christianity and Islam having similar teachings on morals and ethics, or the need for the two largest monotheistic religions to unite to fight against the rise of atheism and alternative spirituality. Chrislam is viewed by some as the solution for the ongoing conflict between the Western world, which is predominantly Christian, and the Middle East, which is predominantly Muslim.
While it is undeniable that there are many similarities between Christianity and Islam (and Judaism, for that matter), Chrislam ultimately fails because Christianity and Islam are diametrically opposed on the most important of issues – the identity of Jesus Christ. True Christianity declares Jesus to be God incarnate. For Christians, the deity of Christ is a non-negotiable, for without His deity, Jesus’ death on the cross would not have been sufficient to be the atoning sacrifice for the sins of the entire world (1 John 2:2).
Islam adamantly rejects the deity of Christ. The Qur’an declares the idea that Jesus is God to be blasphemy (5:17). Belief in the deity of Christ is considered shirk (“polytheism”) to Muslims. Further, Islam denies the death of Christ on the cross (4:157–158). The most crucial doctrine of the Christian faith is rejected in Islam. As a result, the two religions are absolutely not compatible, making Chrislam a concept both Christians and Muslims should reject.
