To Florus 4.117
Suppose, then, that the bishops whose words I am now clearing heard it doubted whether marital union was good. I would ask them whether they acknowledged that bodies were formed by God. Once that was granted, I would add whether they agreed that marriage was ordained by God. With that likewise confirmed, I would ask again whether offspring could exist without union. Once this was denied, what would follow? Clearly, if a body exists only through God, union only through a body, and offspring only through union, then both offspring and union belong to the same author as bodies.
Latin
Ergo si audirent illi sacerdotes, quorum nunc dicta deluimus, dubitari utrum commixtio coniugalis bona esset, atque ab eis peterem corporane a Deo informata, faterentur. Hocque concesso, adderem utrum coniugia a Deo annuerent ordinata. Quo similiter confirmato, peterem denuo, utrum esset sine commixtione fetura. Hocque denegato, quid sequebatur? Videlicet, si nonnisi per Deum corpus, nonnisi per corpus commixtio, nonnisi per commixtionem fetus, ad eumdem auctorem pertinere et fetum et commixtionem, ad quem corpora pertinerent.
