I don't mean ALL Christians, I mean the Christian Church. What other denominations feel I don't know.
Well, lemeesee: We gotcher Catholick Church 'ere, then we gocher Lutherans, then the Episcopalians, and the Methodists over dere, and...Sumbuddy said sumpin' about YOUnitarians, and, oh yeah...dere's them-thar PresBeeTarians, and...Damn! Almost fergot 'bout them Baptists.....
So tell me, Ms. Owlsley, which Christian church from the above list are you referring to -- or are you refering to any number of other Christian Churches that I negelected to mention (the Greek Orthodox Churches are Quite ornate, I am to understand...) ;-\ufffd
Excommunication from the church is Catholic (as far as I know)
Yes, and Lutheran, too, and a number of other Protestant sects also practice it. As do the Mormons (You know, the Church of Jesus Christ of Latter Day Saints). And you certainly can get yerself run out of the Temple of your choice by the local Rabbi. (IIRC Rabbi Jesus of Nazareth did just such a thing on one memorable day....)
A good test would be to propose the Christian Church in question sanctify same-sex marriages in Jesus's name, and see what the half-life of your soul in the eyes of said Church would be....
I wish no one had to go to Hell, I wish God could find other solutions, but since I choose to believe in Him, I am obligated to accept His will, however mystifying or confusing it might be.
Or you could practice a religion where such rubbish is not taught. Buddahism might be a good place to start....
