The relationship between Christianity and violence is a subject of controversy because some have used or interpreted its teachings to justify violence, while others maintain that it promotes only peace, love, and compassion. Despite the example of Jesus, some institutions and individuals have acted violently and attempted to justify themselves through Christian writings.
Heitman and Hagan identify the Inquisition, Crusades, Wars of Religion and antisemitism as being "among the most notorious examples of Christian violence". To this list, Mennonite theologian J. Denny Weaver adds, "warrior popes, support for capital punishment, corporal punishment under the guise of 'spare the rod and spoil the child,' justifications of slavery, world-wide colonialism in the name of conversion to Christianity, the systemic violence of women subjected to men." Charles Kimball, a professor and the author of When Religion Becomes Evil has stated that a strong case can be made that the history of Christianity contains considerably more violence and destruction than that of most other major religions.Diarmaid MacCulloch has also noted that for most of its existence, "Christianity has been the most intolerant of world faiths, doing its best to eliminate all qualified competitors, with Judaism being a qualified exception".
