Readings of the day
Luminous Mysteries
Fifth Mystery: The Institution of the Eucharist
In Advent, the Joyful Mysteries are a natural companion any day.

“This is my body which is given for you. Do this in memory of me.”Luke 22:19
At the Last Supper, on the night before He suffered, Jesus takes bread and wine and gives His Body and Blood to the apostles as food and drink, the new covenant in His Blood.
Fruit of the mystery: Adoration
“O Wisdom” — the O Antiphon for December 17
O Wisdom, who came forth from the mouth of the Most High, reaching from end to end and ordering all things mightily and sweetly: come, and teach us the way of prudence.
Roman Breviary, Magnificat antiphon (translated for this app)
