Today marks the beginning of the Second Theme of Advent in the Catholic Liturgical Calendar. The daily liturgical readings up until today have focussed on Jesus’ second coming and our judgment. Beginning today, the readings focus on the prophecies and events leading to His first coming, a child born of the Virgin Mary. They culminate in the Nativity readings on Christmas Eve.
This beautiful Christmas Day Prayer from Priests for Life:
A Christmas Day Prayer
Praise to You, Lord God!
You have become one of us — You have become a human being, while still retaining all your power and holiness as God!
You, O Lord, made the journey of the unborn child. By being an embryo, a fetus, and a newborn, you joined all unborn and newborn children to you!
From the beginning of history, O Lord, You were the Creator of every human life. Now, with Christmas, You join Yourself in an unthinkable way with the life You created.
Let this Christmas, O God, fill all of us with awe and wonder at how close human life is to You. Cleanse the world of all that tarnishes and rejects this gift. Purify our hearts of all that fears this gift.
Let our Christmas joy be the joy of welcoming every human life! Amen!
