"Calvin took the position that Islam was not merely a threat to European Christendom, but to potential Christians all over the world. Slomp finds Calvin believed that Muslims were former Christians “deceived by Muhammad”. In this way, Calvin placed the blame for Islam as a false religion that sentenced souls to damnation solely on one man, Muhammad. In Calvin’s Opera, Sermon 26 on Daniel 9, he explains that “Muhammad had corrupted the greater part of the world, setting an example for other sects which always want to say and invent something new. All sects that exist today ... have come out of this mud puddle. ”Thus, Muhammad is not merely responsible for Islam as a false religion, but all other sects that have developed since then that mislead the people who, in Calvin’s mind, rightfully belong to Christ. Calvin blames Muhammad for the damned state of all Muslims, citing Muhammad’s “deceitfulness” that has “bewitched” Muslims to idolize him instead of worshipping Christ."
