Origen

“ Celsus ridicules this doctrine because he does not understand it, and because he has learnt it from ignorant persons, who were unable to support it on any reasonable grounds. It will be profitable, therefore, that in addition to what we have said above, we should make this one remark. Our teaching on the subject of the resurrection is not, as Celsus imagines, derived from anything that we have heard on the doctrine of metempsychosis; but we know that the soul, which is immaterial and invisible in its nature, exists in no material place, without having a body suited to the nature of that place. ”

“ Accordingly, it at one time puts off one body which was necessary before, but which is no longer adequate in its changed state, and it exchanges it for a second; and at another time it assumes another in addition to the former, which is needed as a better covering, suited to the purer ethereal regions of heaven. When it comes into the world at birth, it casts off the integuments which it needed in the womb; and before doing this, it puts on another body suited for its life upon earth. ”
