Augustine of Hippo — as excerpted in the Catena Aurea on Luke 18:9-14

“(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.”
