I had to laugh - yep it is much simpler for Roman Catholics!
When it comes to Protestant Christianity .. I gave up LONG ago trying to figure out if I was evangelical or fundmentalist ... or some other label I've never heard of...
I think the labels mean different things to those who consider themselves with the label ... and to those who do not....
As for me - I just believe that in order to get to Heaven - you need to acknowledge that you are a sinner, accept in faith that Jesus came to earth to die and rise again as payment for that sin... all the other stuff is just stuff that man has "interpreted" to make "sense" of it in his (man's) own mind...
