is reincarnation literal ?
or it merely a miss-understanding of spiritual laws that are beyond our comprehension?
I would suggest in any paradigm our eschatalogical state is a matter of speculative rather than literal truth ... unless you happen to hold the
sacra doctrina of that paradigm as axiomatic, in which case one regards the data therein as literally true, even if that to which it alludes is obscure.
Thus many perspectives would argue that certain assumptions of the eschaton itself can be taken as true by virtue of what is believed of its source. Thus for Christians the words of Christ are considered reliable, indeed infallible. And the same goes, I would assume, for the Buddhist — the Buddha is evidence of the truth of the Dharma, if I can say that.
The critical distinction, for the Christian, is the place of the person in the eschaton. Christianity implies it is central. Buddhism and other traditions would seem to imply it is peripheral, and perhaps illusory, the person is not the essence of the existing being, but the accidental phenomena of existence.
Thus Christianity, with its intense focus on the soul, and thereby the person, cannot but refute 'reincarnation' in which the soul appears to have undergone such change as it is not the self it was, it is now another self, another — and other — soul, by which the person is again accidental in regard to whatever it is that reincarnates; the same person does not reappear, one reincarnates as a different person.
Christianity, of course, has resurrection. In this doctrine the selfsame soul and thus the selfsame person are brought back into material existence, something, as I understand it, that Buddhists refute.
Quite how resurrection will work is a mystery that, at present, lies beyond the veil, but as the Christian regards the
kerygma contained within Scripture as revealed truths and infallibly guaranteed, albeit obscurely, we can have faith in the fact that the resurrection will be, when it happens, a literal reality, a reincarnation under precise conditions which other doctrines seem to reject.
As St Paul points out, if there is no resurrection, then our faith and our lives have been for nothing. Sadly (for us) if reincarnation, as understood (as I understand it) in the Asiatic Traditions is true, then we've got the wrong end of the stick ... and it's a long, long stick.
So I would say whether or not it is true, and if true how it is true, depends upon what paradigm you embrace.
