Polls show that about two thirds of Catholics do not believe in Transubstantiation and about ninety percent practice birth control, are they "really" there?
They weren't there to "celebrate", they were there to "hear mass" and "to assist at" the Holy Sacrifice, and the priest was there "to offer" the Holy Sacrifice.
??? How were they doing that when they were praying the rosary or reading other books to pass the time away until their "duty" was completed? Saying the Mass in a foreign language does not increase participation by the congregation.
