Introduction
From December 17 to 23, the Church observes the ancient custom of praying each day one of the seven "O" Antiphons, so called because each one addresses the God who comes in Christ with a different biblical title, beginning with the invocation "O".
In latin, the first letters of the titles, read in reverse order, form the acrostic "Ero cras" which translates as "I will be with you tomorrow." These texts, traced back to seventh-century Europe, are drenched in biblical allusions offering a rich source for personal prayer and reflection during these final days of preparation for the celebration of Christmas.
