December 20
Advent weekday
From December 17 the Advent liturgy turns to the immediate preparation for Christmas, with the great “O Antiphons” at Evening Prayer.
Readings of the day
Luminous Mysteries
Fourth Mystery: The Transfiguration
In Advent, the Joyful Mysteries are a natural companion any day.

“This is my beloved Son. Listen to him!”Luke 9:35
On the mountain, before Peter, James and John, Jesus is transfigured: His face shines and His garments become dazzling white. Moses and Elijah speak with Him, and the Father’s voice comes from the cloud.
Fruit of the mystery: Desire for holiness
“O Key of David” — the O Antiphon for December 20
O Key of David and scepter of the house of Israel, who open and no one shuts, who shut and no one opens: come, and lead the captive from prison, those who sit in darkness and the shadow of death.
Roman Breviary, Magnificat antiphon (translated for this app)
