What amazed me is there is over 30,000 Christian sects, but you think you know the One True Christianity.
A Christian is a Christian when they except Christ as their personal Saviour. Church as in today’s meaning, a sect or a denomination, does not make or break a Christian. There are even Christians who do not follow or belong to any sect or denomination, I am one of them. Going to a church does not make one a Christian, furthermore most if not all churches have many members Christ may not recognize and His. Not going to a church does not mean you are not a Christian.
I do not believe there is one true sect or a denomination. I think there are different sects or a denominations because different people feel called or drawn to different styles of worship. I would attend no church who preached their way was the only way. But then I am more of a tad bit of a cantankerous old fart.
Well, if you would not attend any church who preaches their is the only way, that sure makes thinks a lot easier for you. It probably eliminates about 3/4 of the denominations for you!
Time was when your statement would be true. Not so much any more.
