The Sunday after the Sunday of Zacchaeus is devoted to the Publican and the Pharisee. At Vespers the night before, the TRIODION (the liturgical book used in the services of Great Lent) begins.
Two men went to the Temple to pray. One was a Pharisee who scrupulously observed the requirements of religion: he prayed, fasted, and contributed money to the Temple. These are very good things, and should be imitated by anyone who loves God. We who may not fulfill these requirements as well as the Pharisee did should not feel entitled to criticize him for being faithful. His sin was in looking down on the Publican and feeling justified because of his external religious observances.
The second man was a Publican, a tax-collector who was despised by the people. He, however, displayed humility, and this humility justified him before God (Luke 18:14).
The lesson to be learned is that we possess neither the Pharisee’s religious piety, nor the Publican’s repentance, through which we can be saved. We are called to see ourselves as we really are in the light of Christ’s teaching, asking Him to be merciful to us, deliver us from sin, and to lead us on the path of salvation.
