I think most Christians have forgotten the controversies that gave rise to Protestantism, when it first started. One of the problems had to do with prayers for the dead. The Protestant thinking went like this: since sometimes Church authority has encouraged people to pray and make sacrifices for the dead in a way that seems un-Christian–like asking for money for indulgences–therefore it’s best not to pray for the dead at all.
That controversy has passed into the mists of history. Prohibiting prayers for the dead clearly runs contrary to one of the deepest inclinations of the Christian spirit. But a deeper question, which lay underneath the controversy, still has to be faced, now more than ever: What exactly is the point of a Christian funeral?
#1. Reason numero uno: We believe in the resurrection of the body. The Lord Jesus rose on the third day, in the body with which He had made His earthly pilgrimage, formed originally in the womb of the Virgin. Christ ascended into heaven bodily, flesh of our flesh. And He promised to come again, at which time all the dead will rise from their graves, just like He rose from His.
This is the Christian faith.
During the 20the century, some Christians decided to get fashionable and try to interpret the resurrection of the body, which we confess in our ancient Creed, in a ‘spiritual’ or ‘figurative’ sense. But, as St. Paul put it: that would make us the most pitiable of men. We believe in the promises of Christ more than we believe our own eyes—at least we should believe Christ’s promises more. The dead will rise. We rest in the earth after our bodily death, but not forever.
We have no choice, then, but to treat the bodies of our deceased loved ones with the most loving reverence. This flesh will course with life again. Arbitrarily to destroy the remains of our beloved dead—which is what pagans do—Christians do not do that. Certain things distinguish Christians from pagans—like loving the poor more than money, like having joy in the midst of suffering—and this one: We lavish love upon the bodies of our dead.
