Matthew 9:28

And having brought them into the house, He puts to them a further question. For in many cases He made a point of healing on entreaty, lest any should suppose Him to be rushing upon these miracles through vainglory: and not on this account alone, but to indicate also that they deserve healing, and that no one should say, "If it was of mere mercy that He saved, all men ought to be saved." For even His love to man hath a kind of proportion; depending on the faith of them that are healed. But not for these causes only doth He require faith of them, but forasmuch as they called Him "Son of David," He to lead them up to what is higher, and to teach them to entertain the imaginations they ought of Himself, saith, "Believe ye that I am able to do this?" He did not say, "Believe ye that I am able to entreat my Father, that I am able to pray" but, "that I am able to do this?" What then is their word? "Yea, Lord." They call Him no more Son of David, but soar higher, and acknowledge His dominion.

Yet were they not healed by the way-side and in passing as they had thought to be; but when He was entered into the house, they come unto Him; and first their faith is made proof of, that so they may receive the light of the true faith. And when he was come into the house, the blind men came unto him; and Jesus said unto them, Believe ye that I am able to do this?

He who was able to give sight to the blind, was not ignorant whether they believed; but He asked them, in order that the faith which they bare in their hearts, being confessed by their mouth might be made deserving of a higher reward, according to that of the Apostle, By the mouth confession is made unto salvation. (Rom. 10:10.)

Allegorically; By these two blind men are denoted the two nations of Jews and Gentiles, or the two nations of the Jewish race; for in the time of Roboam his kingdom was Split into two parts. Out of both nations such as believed on Him Christ gave sight to in the house, by which is understood the Church; for without the unity of the Church no man can be saved. And they of the Jews who had believed the Lord's coming spread the knowledge thereof throughout the whole earth.

The house of the ruler is the Synagogue which was ruled by Moses; the house of Jesus is the heavenly Jerusalem. As the Lord passed through this world and was returning to His own house, two blind men followed Him; that is, when the Gospel was preached by the Apostles, many of the Jews and Gentiles began to follow Him. But when He ascended into Heaven, then He entered His house, that is, into the confession of one faith which is in the Catholic Church, and in that they were enlightened.
