Luke 14:19

He who has bought five yoke of oxen is he who neglects his intellectual nature, and follows the things of sense, therefore he cannot comprehend a spiritual nature.

(Serm. 112.) 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.

Or let us suppose that three classes of men are excluded from partaking of that supper, Gentiles, Jews, Heretics. The Jews by their fleshly service impose upon themselves the yoke of the law, for the five yoke are the yoke of the Ten Commandments, of which it is said, And he declared unto you his covenant, which he commanded you to perform, even ten commandments; and he wrote them upon two tables of stone. (Deut. 4:13.) That is, the commands of the Decalogue. Or the five yoke are the five books of the old law. But heresy indeed, like Eve with a woman's obstinacy, tries the affection of faith. And the Apostle says that we must flee from covetousness, lest entangled in the customs of the Gentiles we be unable to come to the kingdom of Christ. (Eph. 5:3, Col. 3:5, Heb. 13:5, 1 Tim. 6:11.) Therefore both he who has bought a farm is a stranger to the kingdom, and he who has chosen the yoke of the law rather than the gift of grace, and he also who excuses himself because he has married a wife.

But whom can we suppose these to be who refused to come for the reason just mentioned, but the rulers of the Jews, whom throughout the sacred history we find to have been often reproved for these things?

(in Hom. 36. in Ev.) By the bodily senses also because they cannot comprehend things within, but take cognizance only of what is without, curiosity is rightly represented, which while it seeks to shake off a life which is strange to it, not knowing its own secret life, desires to dwell upon things without. But we must observe, that the one who for his farm, and the other who to prove his five yoke of oxen, excuse themselves from the supper of their Inviter, mix up with their excuse the words of humility. For when they say, I pray thee, and then disdain to come, the word sounds of humility, but the action is pride. It follows, And this said, I have married a wife, and therefore I cannot come.
