As I said, it obviously isn't an abundance for everyone. You've made that point clearly. 

Catholics certainly assist at the Holy Sacrifice, but I would find it odd if that precluded worship. If you had misgivings about how I intended the term, perhaps the Catholic Encyclopedia at New Advent, or the Catholic Dictionary, also available on line, would relieve your concerns. 

In any event, I'll amend, and offer my sincere hope that you have found a place to assist at the Holy Sacrifice that is to your liking.
