The arrangement of the sanctuary of a church is hardly "the gates of Hell."
The Novus Ordo is hardly "the gates of hell" (though the SSPXers would have you think to the contrary).
I belong to a vibrant parish with 10,000 members, about 6,000 of whom come to Mass every Sunday.
I just can't imagine retrograding to a Tridentine Mass in our parish. That act alone would simply kill it.
Don't worry. The Novus Ordo will be spared the ignominy which befell the Tridentine Rite, when it vanished, almost overnight.
The irony of all this is that those devoted to the Tridentine Rite ask simply for it to be made available. For some reason, this is construed as a threat to the Novus Ordo.
This statistic alone speaks volumes about the fruitfulness of the Novus Ordo. Having only 6 out of 10 parishoners attending Mass weekly would considered disgraceful before Vatican 2.
Let me ask you something: how many vocations has your parish produced since 1970?
Nice to know that 60% of your fellow parishioners show up--apparently 40% don't read the 3rd Commandment and the laws of the Church. In Milwaukee, 100% of Old Rite adherents show up EVERY WEEK----and sometimes far more often, for Mass.
Just a minor difference.
