to answer the question “why face the people”, these are the reasons I have heard (which my comments in parentheses)
-the Eucharist is a meal (they forget the Mass is a Sacrifice primarily)
-this is how the Last Supper was (I’m not so sure it was, but like the first point … the Mass is not just the last supper, the Mass is also Calvary)
-we are all one church together (we are a Church founded by God and should be directed to Him)
-the priest should not turn his back to us (the priest should not turn his back to the Tabernacle)
There is also the influence of the protestants their forms of worship.
Some priests actually want people to look at them and put their personality into the Mass.
At the most extreme, what good is clown makeup if the congregation can’t see it?
Another reason: some people would use any excuse to wreck churches and make changes, disregard the high altar, use new altars without relics, etc. etc. etc. To such people: old bad, new good.
