See here, the camel disencumbered of his hunch passes through the eye of a needle, that is, the rich man and the publican abandoning his love of riches, and loathing his dishonest gains, receives the blessing of his Lord's company. It follows, And he made haste, and came down, and received him joyfully.
Zacchaeus is called the son of Abraham, not because he was born of Abraham's seed, but because he imitates his faith, that as Abraham left his country and his father's house, so he abandoned all his goods in giving them to the poor. And He well says, “He also,” to declare that not only those who had lived justly, but those who are raised up from a life of injustice, belong to the sons of promise.
Mystically, Zacchaeus, which is by interpretation “justified,” signifies the Gentile believers, who were depressed and brought very low by their worldly occupations, but sanctified by God. And he was desirous to see our Savior entering Jericho, inasmuch as he sought to share in that faith which Christ brought into the world.
Or the crowd that is, the general habit of vice, which rebuked the blind man crying out, lest he should seekthe light, also impedes Zacchaeus looking up, that he might not see Jesus; that as by crying out the more the blind man overcame the crowd, so the man weak in the faith by forsaking earthly things, and climbing the tree of the Cross, surmounts the opposing multitude. The sycamore, which is a tree resembling the mulberry in foliage, but exceeding it in height, whence by the Latins it is called “lofty,” is called the “foolish fig-tree,” and so the Cross ofour Lord sustains believers, as the fig-tree figs, and is mocked by unbelievers as foolishness. This tree Zacchaeus, who was little in stature, climbed up, that he might be raised together with Christ; for every one who is humble, and conscious of his own weakness, cries out, God forbid that I should glory, save in the cross of our Lord Jesus Christ.
The Lord as He journeyed came to the place where Zacchaeus had climbed the sycamore, for having sent His preachers throughout the world in whom He Himself spoke and went, He comes to the Gentile people, who were already raised up on high through faith in His Passion, and whom when He looked up He saw, for He chose them through grace. Now our Lord once abode in the house of the chief of the Pharisees, but when He did works such as none but God could do, they railed at Him Wherefore hating their deeds He departed, saying, Your house shall be left to you desolate; but now He must needs stay at the house of the weak Zacchaeus, that is, by the grace of the new law brightly shining, He must take rest in the hearts of tile lowly nations. But that Zacchaeus is bid to come down from the sycamore tree, and prepare an abode for Christ, this is what the Apostle says, Yea,though we have known Christ after the flesh, yet now henceforth know we Him no more. And again elsewhere, For though he was crucified through weakness, yet he lives by the power of God. It is plain that the Jews always hated the salvation Of the Gentiles; but salvation, which formerly filled the houses of the Jews, has this day shone upon the Gentiles, forasmuch as this people also by believing on God is a son of Abraham.
