No, it is just Christianity that is the demarcation. I’m saying that when you have American evangelicalism (which functions as a social club, and is not moored by anything other than “get people in the door”) as your delivery mechanism, you’re less likely to get solid catechisis. This is of course not impossible, I know many bad catholic Christian’s and many good Protestant Christians, but your odds of getting the good news delivered correctly are higher in more orthodox settings.
