The liberal National Catholic Reporter has an article about cadaver shows, noting the disparity of approaches by Catholic dioceses.
It is interesting to read the comments–a couple of which are clearly more pagan than Christian. E.g.:
The body is a temporary vessel where physical human existence can take place on this plane. … It is, in my opinion, … a reminder that this earthly existence of ours will some day be over and we will all be reduced to a state where no one person is better than another.
When death occurs, the soul leaves the body, leaving nothing more than a hollow empty husk. A husk that eventually returns to the dust it came from. Since there is no soul in the body, what difference does it make what happens to it?
