The O antiphons are verses of praise used during the last seven days of Advent (December 17-23). They are referred to as the "O Antiphons'' because the title of each one begins with the "O" addressing a given title in the verse to Christ. Each antiphon is a reflection on the name of Christ, and praise of one of his attributes mentioned in Scripture.
