So everyone else, enjoy the resulting myriad of options, and choose whatever strain of being "Christian" appeals to you personally in your present moment today, especially if it's something extremely popu-lare.. on tv.
Personally, I still find error in the Catholics, but I already know the offshoots are just politically based, and thus definitely the wrong path.. well, in my search, at least. I'd be glad to hear any authoritative contrarian speak to me on that, and would be very respectful to their rebuttal.
I cannot speak for others.
