Quite honestly, I don’t think there will be any sort of significant split. You can watch the news, listen to the anti-Catholics, and nitpick over the details til you turn blue in the face, but when you get right down to it, the vast majority of the Parishes in this country are perfectly happily in communion with Rome.
There are social and intellectual orthodoxies in this country that have crept their way into people’s habits and beliefs for sure, and we have an unfortunate culture of people not going out of their way to learn and study the faith, but for the most part Catholics understand the major tenets of the Church. It’s not as bad as it seems.
As has been mentioned before, a lot of this is just the calming of the storm that naturally comes after a council as major as Vatican II. Time will smooth things over, and I firmly believe that most Priests and Bishops will realize that now is the time we have to stand strong and stand together. I actually predict that we’ll be blessed to witness the emergence of new Saints the caliber of Aquinas and Francis of Assisi in this generation that will serve to renew and refresh the faith.
That has ALWAYS been God’s response for the Church in the darkest of times. And we’ll come out a FAR better Church for it.
