On the evening of December 17 the final phase of preparation for Christmas begins with the first of the great "O Antiphons" of Advent.
The "O Antiphons" were first used by the Church in the 8th and 9th centuries. They are based on various titles for the Christ and are scripturally-based short prayers for the 17th to the 23rd of December.
In these "O Antiphons" the Church expresses her deep longing for the coming of the Messiah.
It is especially in the final week of Advent that our attention is fixed on the messianic promises proclaimed by the ancient prophets of Israel.
The seven titles attributed to Jesus in the antiphons are Wisdom (Sapientia in Latin), Ruler of the House of Israel (Adonai), Root of Jesse (Radix), Key of David (Clavis), Rising Dawn (Oriens), King of the Gentiles (Rex). and Emmanuel. In Latin the initials of the titles make an acrostic which, when read backwards. means: "Tomorrow I will be there" ("Ero cras"). To the medieval mind this was clearly a reference to the approaching Christmas vigil
They can be prayed at family dinner times or with the lighting of the Advent wreath
