As best as I have been able to understand, V2 didn’t forbid Roman Catholics from continuing their extant practices. It opened up more options and more relaxed modes of religious practice. I’ve seen a lot of Catholics that think V2 opened up a bigger can of worms than it put to rest, and choose the older practices, but who are not in congregations that are dedicated to opposing it.
If that was all it did then there would not be schisms because of it. www.the-pope.com/wvat2tec.html
Have a God night.
