In my post was the concept of the soul separating from the body and "moving on". That is what I believe, and that aligns nicely with my Christian beliefs. Reverence for a dead body seems pagan.
"Reverence" for dead bodies is something a step above what's being discussed, which is simple respect.
The idea of treating dead bodies with respect is hardly pagan. In the Old Testament, the Hebrew religion specifically required that it was a religious duty to bury the dead. The Book of Tobit, for example, revolves around the whole drama of an exiled Israelite man gets in big trouble for insisting on burying his fellow countrymen when the Assyrian overlords had forbidden it. In the New Testament we see this practice of making sure people had an honorable burial continue. The Church has always numbered the obligation by Christians to bury the dead as one of the 'Corporal Acts of Mercy".
