Bede the Venerable
Catena Aurea · Lukasevangelium 18
And he spake this parable unto certain which trusted in themselves that they were righteous, and despised others: Two men went up into the temple to pray; the one a Pharisee, and the other a Publican. The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this Publican. I fast twice in the week, I give tithes of all that I possess. And the Publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote upon his breast, saying, God be merciful to me a sinner. I tell you, this man went down to his house justified rather than the other: for every one that exalteth himself shall be abased; and he that humbleth himself shall be exalted.
Typically, the Pharisee is the Jewish people, who boast of their ornaments because of the righteousness of the law; but the Publican is the Gentiles, who being at a distance from God confess their sins. Of whom the one for His pride returned humbled, the other for his contrition was thought worthy to draw near and be exalted.
