Collect for the Fourth Sunday in Advent

This is the collect for the Fourth Sunday of Advent in the Extraordinary Form. It is also the prayer we say (this week) after singing O Come O Come Emmanuel around our Advent Wreath.


We know this one less well, as it is rarely said for the full week (depending, of course, on which day of the week Christmas is).  This year we do get a full week's worth, so I hope it will be committed to memory with the others...

Arise we beseech thee O Lord in thy strength, and come in might to our aid; that by the work of thy grace, that good to which our sins are a sore hindrance may, in the fullness of thy forgiveness, speedily be vouchsafed to us.
