Provided there is pollution, it is indifferent whether the beast be male or female, of what species it may be, or by what part the act is performed, since the malice of this sin consists in approach to a different species, with which generation cannot be had. It is a graver sin than even sodomy, since in this sin the same species is not kept. It is established today that generation does not follow from the intercourse of a man with a beast.
Dummodo adsit pollutio indifferens est sive bestia sit masculina sive feminina, qua specie sit, vel qua parte coeatur, cum malitia hujus peccati consistat in accessu ad diversam speciem, quacum generatio haberi non possit. Gravius est peccatum quam etiam sodomia, cum in hoc peccato non servetur eadem species. Constat vero hodie generationem non sequi ex commercio hominis cum bestia.
