“But the tax collector stood off at a distance and would not even raise his eyes to heaven but beat his breast and prayed, ‘O God, be merciful to me a sinner.’ I tell you, the latter went home justified, not the former; for everyone who exalts himself will be humbled, and the one who humbles himself will be exalted.” (Lk 18:9-14)

The Parable of the Publican and the Pharisee is the source of the Jesus Prayer: ¨Lord Jesus Christ, Son of God, have mercy on me, a sinner.¨ After the Resurrection, the Virgin Mary remained in prayer with the disciples and ever since has always been a symbol of a heart in tune with God.
