“That is the trouble with the gospel. It’s too simple.”
If that’s true why you have the 1,000s of competing Protestant interpretations of the Gospel?
Protestants see this come up quite frequently. Protestants, for the most part, do not have "competing" interpretations of the Gospel. I have attend numerous churches in my life and have never had a problem with worshiping with any Protestants except liberals or mega-churches that preach a water-down version of the gospel. We may differ on some issues, but on the substantive issues we concur.
I'm sure you see my point. I would hope most Catholics would not support the Hindu Mass, a Buddhist mass, or even using dragons in masses to promote racial harmony. However, mass is mass. It doesn't matter what shenanigans goes on. Good Catholics (sometimes) just wring their hands and bemoan the fact that their political religious leaders are taking them down a bad path but the Holy Spirit will ultimately guide the Church. Of course, then again, there was that thing that happened with Luther so one has to wonder how that logic really works. For other Catholics they thing it's grand. And the Vatican really doesn't mind what goes on in Mass as long as attendance is up and the coffers remain full. They often chaulk it up to diversity even if it involves incorporating pagan rituals.
Hmmmm....in retrospect perhaps on some things Catholics and Protestants aren't so terribly different.
