I had an email from that very sweet lady at Gloria TV, with a bright idea.
The international Catholic web-page Gloria.TV is holding a special on-line retreat this Advent concentrated on the O-antiphons .
The retreat will be given by Gloria.TV's own Father Reto Nay.
One of the most familiar of the Advent hymns is "O Come, O Come, Emmanuel," with the seven traditional "O Antiphons" being more than a thousand years old. They are used at the very end of Advent (Dec. 17-23) in the liturgical prayer of the Church and are sung or recited during Vespers (the Evening Prayer of the Liturgy of the Hours).
