This is why, for instance, Roman Catholicism forbids scattering ashes (and until recently forbid cremation at all). Of course no one claims that God is somehow incapable of resurrecting a mutilated, cremated, scattered, etc. body but can resurrect an ordinarily decomposed one. But the act of scattering ashes demonstrates a fundamental misunderstanding of Christian burial practices. Human remains are placed in safekeeping for the last day, in expectation of resurrection on earth. It is not the case that the soul departs to heaven and the body becomes irrelevant, and that therefore doing something symbolic and/or environmentally responsible with the ashes is reasonable. Christian burial, under normal circumstances, involves putting the remains in some definite place and putting a headstone on it.
So in turn the traditional Christian burial rites have used text about committing the body to the earth, in normal cases, or to the sea, for sailors lost at sea, trusting the earth or sea with that safekeeping. Here's a 1789 Book of Common Prayer rite, which quotes a few of the passages I mentioned: http://justus.anglican.org/resources/bcp/1789/Burial_1789.ht...
In particular, burial at sea involves the following prayer:
We therefore commit his body to the deep, looking for the general Resurrection in the last day, and the life of the world to come, through our Lord Jesus Christ; at whose second coming in glorious majesty to judge the world, the sea shall give up her dead; and the corruptible bodies of those who sleep in him shall be changed, and made like unto his glorious body; according to the mighty working where by he is able to subdue all things unto himself.
That's the sort of prayer being referenced by Nixon's speechwriter.
I'm genuinely baffled at the popularity of the idea that your soul immediately goes and lines up at the Pearly Gates, and then you stay in either heaven or hell forever. It's possible to find evidence to support that model, yes; for instance a literal reading of the the parable of the rich man and Lazarus (no relation to Lazarus of Bethany) would imply it. But there's quite a lot of direct statements saying otherwise.
Huh, even to the extent of adding explicit test cases for observed bugs (heresies).
I was too distracted by the test-suite point to notice that I should quarrel with this: it refers to "ἀνάστασι[ς] νεκρῶν" (Lat. "resurrectio[] mortuorum"), where νεκροί are the dead, not specifically their bodies (σώματα).
(It's true that some Christians who believe in the resurrection at the last day believe in "soul sleep" until then, and they'd answer you that the repentant thief will not perceive passage of time between death and resurrection and that's what "today" means; I'll gladly acknowledge that that's a shaky argument. But the concept of the resurrection is far more universal than the concept of soul sleep.)
The gender of objects depend a lot of the language you speak (and culture). For example in Spanish the Sun is male and the Moon is female, but in German the Sun is female and the Moon is male.
