Catena Aurea · Lukasevangelium 14
And when one of them that sat at meat with him heard these things, he said unto him, Blessed is he that shall eat bread in the kingdom of God. Then said he unto him, A certain man made a great supper, and bade many: And sent his servant at supper time to say to them that were bidden, Come; for all things are now ready. And they all with one consent began to make excuse. The first said unto him, I have bought a piece of ground, and I must needs go and see it: I pray thee have me excused. And another said, I have bought five yoke of oxen, and I go to prove them: I pray thee have me excused. And another said, I have married a wife, and therefore I cannot come. So that servant came, and shewed his lord these things. Then the master of the house being angry said to his servant, Go out quickly into the streets and lanes of the city, and bring in hither the poor, and the maimed, and the halt, and the blind. And the servant said, Lord, it is done as thou hast commanded, and yet there is room. And the lord said unto the servant, Go out into the highways and hedges, and compel them to come in, that my house may be filled. For I say unto you, That none of those men which were bidden shall taste of my supper. For in these latter times, and as it were the setting of our world, the Son of God has shone upon us, and enduring death for our sakes, has given us His own body to eat. Hence also the lamb was sacrificed in the evening according to the Mosaic law. Rightly then was the banquet which was prepared in Christ called a supper.
By this servant then who is sent by the master of the family to bid to supper, the order of preachers is signified. But it is often the case that a powerful person has a despised servant, and when his Lord orders any thing through him, the servant speaking is not despised, because respect for the masterwho sends him is still kept up in the heart. Our Lord then offers what he ought to be asked for, not ask others to receive. He wishes to give what could scarcely be hoped for; yet all begin at once to make excuse, for it follows, And they all began with one consent to make excuse. Behold a rich man invites, and the poor hasten to come. We are invited to the banquet of God, and we make excuse.
