Some branches of Christianity entirely oppose cremation, including non-mainstream Protestant groups and the Orthodox churches. Most notably, the Eastern Orthodox and Oriental Orthodox Churches historically forbid cremation, but not dogmatically. Exceptions are made for circumstances where it cannot be avoided (when civil authority demands it, in aftermath of war or during epidemics) or if it may be sought for good cause. But when a cremation is specifically and willfully chosen for no good cause by the one who is deceased, he or she is not permitted a funeral in the church and may also be permanently excluded from burial in a Christian cemetery and liturgical prayers for the departed. In Orthodoxy, cremation is perceived as a rejection of the temple of God and of the dogma of the general resurrection.
