One of the main deciding factors in whether or not one chooses cremation usually has to do with their relgious beliefs. Because of that, I have scoured the internet and have gathered information on 13 different religions, and their general standards regarding cremation. Obviously, one can choose whatever they wish....however, if religion is a sticking point for you, then I hope this helps. So here it is, 13 religions, and their beliefs on cremation
Anglican/Episcopalian Cremation is acceptable for Episcopalians and will not interfere with holding a traditional Episcopal funeral.
Baptist There is no ban on cremation for members of the Baptist faith, and cremation may take place either before or after the funeral service.
Buddhist Cremation is acceptable in Buddhism. If the body is to be cremated, monks may be present at the crematorium and lead chanting. If no monks are present, family members may lead chanting. Cremated remains may be collected by the family the following day, and may be kept by the family, enshrined in a columbarium or urn garden, or scattered at sea.
Catholic Historically, the Catholic Church has not supported cremation. However, these days it is acceptable for a Catholic to be cremated. That said, most churches prefer that the body be present for the Funeral Mass, meaning that cremation should occur after the Funeral Mass. Remains should be buried in the ground or at sea or entombed in a columbarium, and should not be scattered.
Eastern Orthodox Cremation is prohibited in the Eastern Orthodox Church.
Hindu Traditionally, all Hindus—except babies, children, and saints—are cremated.
Jewish Depending on the degree of orthodoxy of the deceased, the rules around cremation may vary. For Orthodox Jews, cremation is not acceptable and the body should be buried, intact, in the ground. While cremation is opposed by Conservative Jews, a Conservative rabbi may still perform a funeral for a person who has been cremated. However, in most Conservative communities, the rabbi will not be present for the interment of the ashes. For Reform Jews, however, cremation is becoming an increasingly common practice, and most Reform rabbis will willingly perform a funeral and interment for someone who has been cremated.
Lutheran Cremation is acceptable for Lutherans and will not interfere with holding a traditional Lutheran funeral.
Methodist Cremation is acceptable for Methodists, and will not interfere with holding a traditional Methodist funeral.
Mormon While cremation is not prohibited for Mormons, it is not encouraged, and the Church prefers that bodies be buried rather than cremated.
Muslim Cremation is forbidden for Muslims.
Presbyterian Though there is no clear commandment against cremation, Presbyterians generally do not support cremation, and instead prefer that the body remain intact and be buried in the ground.
Quaker There are no religious criteria for interment, and thus Quakers may be buried or cremated.
