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.
(Serm. 115.) Why then marvel ye, whether God pardons, since He himself acknowledges it. The Publican stood afar off, yet drew near to God. And the Lord was nigh unto him, and heard him, For the Lord is on high, yet hath he regard to the lowly. He lifted not so much as his eyes to heaven; that he might be looked upon, he looked not himself. Conscience weighed him down, hope raised him up, he smote his own breast, he exacted judgment upon himself. Therefore did the Lord spare the penitent. Thou hast heard the accusation of the proud, thou hast heard the humble confession of the accused. Hear now the sentence of the Judge; Verily I say unto you, this man went down to his house justified rather than the other.
