Beginning the Church's liturgical year, Advent is the season leading up to the celebration of Christmas. The Advent season is a time of preparation that directs our hearts and minds to Christ’s second coming at the end of time and also to the anniversary of the Lord’s birth on Christmas. Advent devotions remind us of the meaning of the season. Special Advent Devotions: the lighting of the Advent wreath; the Advent calendar helps remind us of the season with daily thoughts and activities; Advent prayers prepare us spiritually for the birth of Jesus Christ.
The season to celebrate the Lord's birth, his manifestation to the world, and His baptism. The season begins Christmas eve and ends on the Baptism of the Lord, including the Epiphany of the Lord as well.
