The majority of Christians live in a situation of religious freedom in democracies. Has Christianity become a major focus of persecution? Yes, approximately 10% of them live as minorities in an ever growing hostile environment. By exploring ten factors behind the persecution of Christians, the article shows that persecution is a complex phenomenon. The article discusses the major reasons for persecution of Christians and sees religious fundamentalism—defined as a militant truth claim—in the major world religions of Islam, Hinduism, and Buddhism, as the major reason for the growing number of Christians being killed and churches being destroyed. The four other reasons are religious nationalism, the displacement from Islamic countries of long-established Christian churches, limitations on freedom of religion, and the special price paid by converts from Islam and Hinduism. A take away from this article is that while individual Christians ought not to retaliate, Christians around the world should hold governments in which persecution occurs accountable.
