The Nativity of Christ (source)
"Now we are on our way to venerate the Nativity of our Christ. What shall we tell Him? What will show our worth to Him? Now is truly the hour to gather a little care, a little painful work, a little self-denial, a little humility, a little self-reproach, so that we might say with fervor before the Infant: 'O All-Good One, have you come for me? Receive me the poor one! I don't have anything!" This He desires. He desires nothing else."
-Elder Joseph of Vatopedi

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
