The St Andrew Christmas Novena

Sort of.

It's not really to St Andrew; but it begins, depending upon which tradition you follow,  on his feast day or on the 1st Sunday of Advent which is the Sunday nearest his feast day.  This year that's the same thing.  And it's not really a novena which is supposed to last nine days.

But it's a beautiful prayer tradition for the season.  The prayer is this:

Hail and blessed be the hour and moment in which the Son of God was born of the most pure Virgin Mary, at midnight, in Bethlehem, in piercing cold. In that hour, vouchsafe, O my God! to hear my prayer and grant my desires, through the merits of Our Saviour Jesus Christ, and of His Blessed Mother. Amen.

The tradition is to pray it 15 times a day until Christmas.  There are many mentions of it on the web but no site goes very deeply, or indeed at all,  into its history.  Mrs Vidal says as much as anyone here. There's another mention here. It seems that's as much as we're going to learn about it. My grandmother knew it and so as a good traditionalist, I've adopted it.
