Maybe that's why they do it in committees?

Translate the mass, that is. I've been trying since Sunday to make a translation of the mass of Our Lady of Lourdes, according to the 2002 revised Roman Missal, but I'm stuck on some parts.The preface has me stumped, and the prayer over the offerings I don't have the last line translated yet. Maybe it'll be done by Sunday. I'm using Common II of the Blessed Virgin, which is the mass that the collect for the day is based on.
