Pseudo-Chrysostom
Catena Aurea · Matthäusevangelium 7
Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.
Or; The swine not only trample upon the pearls by their carnal life, but after a little they turn, and by disobedience rend those who offend them. Yea often when offended they bring false accusation against them as sowers of new dogmas. The dogs also having trode upon holy things by their impure actions, by their disputings rend the preacher of truth.
