"Of course, every time someone comes up with a new interpretation of Scripture he or she goes off to form "The One True Church."
Can you document that every single denomination claims to be the "one true church?" Many denominations are formed over minor preferences in style of worship. Actually, most Christian denominations today are respectful of each other, and acknowledge that they have more in common than not.
The church of Christ is a body of believers, not a "denomination," establishment, building, or bureaucratic organization.
As one of the evo posters says, there are bitter differences of opinion about the details of biology also.
Just go onto any of the religious threads in the religion forum...there you will find many major disagreements going on, about just what the Bible is saying...for some churches, there may be small differences between them and other churches, but there are also many major differences that are argued about and discussed every day here on FR, in the religious forums...and they can get every bit as nasty as any of the CREVO threads get...the religion moderator works overtime, I do believe, keeping the posters in check...the religion moderator even has special rules for the religious threads, rules which are even stricter than on the other threads...take a look at those threads, you might be surprised at what you find there...
I can name two from personal experience.
Many of my friends are Lutherans, and the churches they attend all believe that the Pope is the antichrist.
I was a member of a non-denominational fundamentalist church (a long time ago, in a galaxy far, far away) that was an offshoot of the Four-Square church. The majority of the congregation (and the pastor) believed that all other churches were pagan, and going to hell.
The true church (also referred to Biblically as saints) is composed of any/all true believers in Jesus Christ as Lord and Saviour. 2 other things: I have met many from various and sundry christian persuasions who I believe are true christian saints but only God knows the true heart and beliefs of those who profess and claim belief in Christ. Paraphrased: Many will come knocking at the door saying Lord Lord and claiming great wonders and miracles in His name and Jesus will say depart because I knew you not.
