Tertullian

“ To put a complete stop, however, to the sowing of the human race, may, for aught I know, be quite consistent for Marcion’s most good and excellent god. For how could he desire the salvation of man, whom he forbids to be born, when he takes away that institution from which his birth arises? How will he find any one on whom to set the mark of his goodness, when he suffers him not to come into existence? ”

“ So likewise the state of matrimony does not require the hook and scythe of sanctity, as if it were evil; but as being ripe for its discharge, and in readiness for that sanctity which will in the long run bring it a plenteous crop by its reaping. For this leads me to remark of Marcion’s god, that in reproaching marriage as an evil and unchaste thing, he is really prejudicing the cause of that very sanctity which he seems to serve. For he destroys the material on which it subsists; if there is to be no marriage, there is no sanctity. All proof of abstinence is lost when excess is impossible ”

“ Let us see, then, whether it be a just one: not as if we aimed at destroying the happiness of sanctity, as do certain Nicolaitans in their maintenance of lust and luxury, but as those who have come to the knowledge of sanctity, and pursue it and prefer it, without detriment, however, to marriage; not as if we superseded a bad thing by a good, but only a good thing by a better. For we do not reject marriage, but simply refrain from it. ”
