You know, I was on another forum and visited a thread that had primarily roman catholic and eastern orthodox people in it. Then somebody claimed that there church was the "one true church" And let me tell you. That thread exploded into a war, a war of insults, where some people said some very VERY not nice things about some other people. You think they were trying to kill each other with words.
Tell me, why do some christians need there church to be the "one true church"?
1 John 4:19 "If a man say, I love God, and hateth his brother, he is a liar..."
I suspect that if you quoted this in the middle of such debate, some would respond that the other party "is no brother of mine" which is merely an ungodly excuse to hate.
The fact is, religious people
need validation from others, because they don't really
believe in the Christ Who is able to save them. What keeps them in bondage is that they are told by their leaders that their church is the only one acceptable to God (the "one true church"), but the fact is, that God doesn't accept
any of them. God only accepts individual believers in Christ, who exhibit their faith by the love they express for all believers everywhere, and this is the "one true" universal church. The difference is that the true church is made up of true believers everywhere, and the "churches" which are called that by religious people are made up of both true and false believers.
Therefore, I say that any time we come across a debate like the one you described, we should quote 1 John 4:19-21 in full force. Then the true and false believers will become evident, as the true believers will immediately repent.
