Advent and Christmas bring into our present awareness the future, present and past comings of the Incarnate Son of God.
The word "advent" comes from the Latin "adventus" meaning "arrival" or "coming," particularly of something having great importance.
During Advent, the church remembers the important comings of our Lord and Savior Jesus Christ. It starts by looking forward, in hope, to Jesus’ future coming in glory.
It then considers Jesus’ continuing present coming to us through the Holy Spirit.
Then it concludes with a joyous remembering of the Son of God’s coming to us in the flesh through the miracle of the Incarnation. This leads into the celebration of Jesus’ birth on Christmas Day.
