Catena Aurea on Luke 14:15–24: Augustine of Hippo

The five yoke of oxen are taken to be the five senses of the flesh; in the eyes sight, in the ears hearing, in the nostrils smelling, in the mouth taste, in all the members touch. But the yoke is more easily apparent in the three first senses; two eyes, two ears, two nostrils. Here are three yoke. And in the mouth is the sense of taste which is found to be a kind of double, in that nothing is sensible to the taste, which is not touched both by the tongue and palate. The pleasure of the flesh which belongs to the touch is secretly doubled. It is both outward and inward. But they are called yoke of oxen, because through those senses of the flesh earthly things are pursued. For the oxen till the ground, but men at a distance from faith, given up to earthly things, refuse to believe in any thing, but what they arrive at by means of the five-fold sense of the body. “I believe nothing but what I see.” If such were our thoughts, we should be hindered from the supper by those five yoke of oxen. But that you may understand that it is not the delight of the five senses which charms and conveys pleasure, but that a certain curiosity is denoted, he says not, I have bought five yoke of oxen, and go to feed them, but go to prove them.
