Luke 19:31

What then was the sign? He sat on a colt, as we have just heard the blessed Evangelist clearly telling us. Perhaps someone will say, "When he traveled all Judea—for he taught in their synagogues and added the working of miracles to his words—he did not ask for an animal on which to ride. When Christ could have purchased one, he would not, although he often was wearied by his long journeys on the way. When passing through Samaria, he was wearied with his journey, as it is written. Who can make us believe that when he was going from the Mount of Olives to Jerusalem, places separated from one another by so short an interval, that he would require a colt? Since the mother accompanied the colt, why did he not take the mother instead of choosing the colt? The donkey that bore the colt was brought to him also. We learn this from the words of Matthew, who says that he sent the disciples to a village opposite them. He said to them, "You will find a donkey tied and a colt with her. Untie and bring them to me." "They brought," it says, "the donkey and the colt with her." We must consider, therefore, what are the explanations and the benefits that we derive from this occurrence and how we make Christ riding on the colt a type of the calling of the Gentiles. The colt of a donkey is mounted on which none has sat, because no one before Christ called the peoples of the nations to the church.

(Hom. 66. in Matt.) At the beginning of His ministry our Lord showed Himself indifferent to the Jews, but when He had given sufficient token of His power, He transacts every thing with the highest authority. Many are the miracles which then took place. He foretold to them, ye shall find an unbroken colt. He foretels also that no one should hinder them, but as soon as they heard it, should hold their peace.

Here it was evident that there would be a divine summons. For no one can resist God calling for what is His own. But the disciples when ordered to fetch the colt refused not the office as a slight one, but went to bring him.

And the prophecy, "He shall be the expectation of the nations," signified that there would be some of all nations who should look for Him to come again. And this indeed you can see for yourselves, and be convinced of by fact. For of all races of men there are some who look for Him who was crucified in Judaea, and after whose crucifixion the land was straightway surrendered to you as spoil of war. And the prophecy, "binding His foal to the vine, and washing His robe in the blood of the grape," was a significant symbol of the things that were to happen to Christ, and of what He was to do. For the foal of an ass stood bound to a vine at the entrance of a village, and He ordered His acquaintances to bring it to Him then; and when it was brought, He mounted and sat upon it, and entered Jerusalem, where was the vast temple of the Jews which was afterwards destroyed by you.

Thirdly, as regards the authoritative command through the summit of supreme authority, there is added: And if anyone asks you: Why are you loosing it? namely, handling another's property; you shall say thus to him: Because the Lord desires its service, so that he may …
