It's true that in the modern era the Catholic Church actually forbade the practice of cremation except in cases of public necessity. My understanding is that this had absolutely nothing to do with the Catholic belief in the ultimate resurrection of the body, which according to their theology will occur miraculously regardless of how the original body's component molecules were dispersed. Indeed, the rejection of cremation apparently was not based on any resistance to the practice itself, but rather to certain pagan or anti-Catholic ideologies that have historically been associated with cremation (including, notably, Freemasonry).zakur said:He's probably a conservative Catholic. According to the Catechism of the Catholic Church, our bodies will be resurrected:It is my understanding that it is for this reason that the Catholic Church banned the practice of cremation until the 1960s, and until recently (late 1990s?), would not allow cremains in a Church during funeral mass.
In 1983 the canon law was changed to allow Catholic cremations "unless it has been chosen for reasons which are contrary to Christian teachings".
I'm not aware of anything in Catholic theology that would oppose someone's donation of his body to science.
