The Following is an excerpt from Great Lent, by Alexander Schmemann
From Chapter 2: Preparation for Lent
The next Sunday [after Zaccheus Sunday] is called the "Sunday of the Publican and the Pharisee." On the eve of this day, on Saturday at Vespers, the liturgical book of the Lenten season-- the Triodion-- makes its first appearance and texts from it are added to the usual hymns and prayers of the weekly resurrection service. The develop the next major aspect of repentance: humility.
The Gospel lesson (Lk. 18:10-4) pictures a man who is always pleased with himself and who thinks that he complies with all the requirements of religion. He is self-assured and proud of himself. In reality, however, he has falsified the meaning of religion. He has reduced it to external observations and he measures his piety by the amount of money he contributes to the temple. As for the Publican, he humbles himself and his humility justifies him before God. If there is a moral quality almost completely disregarded and even denied today, it is indeed humility. The culture in which we live constantly instills in us the sense of pride, of self-glorification, and of self-righteousness. It is built on the assumption that man can achieve anything by himself and it even pictures God as the one who all the time "gives credit" for man's achievements and good deeds. Humility-- be it individual or corporate, ethnic or national-- is viewed as a sign of weakness, as something unbecoming a real man. Even our churches-- are they not imbued with that same spirit as the Pharisee? Do we not want our every contribution, every "good deed," all that we do "for the Church" to be acknowledged, praised, publicized?
