Augustine of Hippo
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.
If you look into his words, you will find that he asked nothing of God. He goes up indeed to pray, but instead of asking God, praises himself, and even insults him that asked. The Publican, on the other hand, driven by his stricken conscience afar off, is by his piety brought near.
