The dialogue Mass was the last public, modernist step toward the novus ordo mess.
Make the people feel important, stroke their egos, get them to stop praying and just wait for their next turn to speak their part.
The dialogue Mass was not what Pope St Pius X meant when he introduced the missal to the laity; but as always the modernists jumped quickly to hijack the opportunity to turn it to their advantage.
I believe this is what got the liberal women (wannabe priests) all fired up to take over in the churches. And down the slippery slope we went!
And this is what the SSPX is teaching in their school chapels.
