Tertullian

“ For when once a man is fallen or removed from the sure hope which he had placed in the Creator, he is easily led away to the object of a different hope, whom however of his own accord he can hardly help suspecting. Now it is by a discrepancy in the promises that a difference of gods is insinuated. How many do we thus see drawn into the net vanquished on the resurrection of the flesh, before they could carry their point on the oneness of the Deity! In respect, then, of the heretics, we have shown with what weapons we ought to meet them. ”

“ For if the resurrection of the flesh be denied, that prime article of the faith is shaken; if it be asserted, that is established. There is no need, I suppose, to treat of the soul’s safety; for nearly all the heretics, in whatever way they conceive of it, certainly refrain from denying that. We may ignore a certain Lucan, [12] who does not spare even this part of our nature, which he follows Aristotle in reducing to dissolution, and substitutes some other thing in lieu of it. Some third nature it is which, according to him, is to rise again, neither soul nor flesh ”

“ No procedure, indeed, can be more reasonable. And we affirm that controversy with heretics should in most cases be conducted in this way. For due method requires that conclusions should always be drawn from the most important premises, in order that there be a prior agreement on the essential point, by means of which the particular question under review may be said to have been determined. Hence it is that the heretics, from their conscious weakness, never conduct discussion in an orderly manner. ”
