Then you should leave whatever apostate denomination you belong to and join with an evangelical independent or denominational church that still believes the bible in it's entirety and preaches the same biblical Sola Vida gospel plan of salvation by grace through faith in Christ alone that the Apostles received by divine inspiration and preached over 19 centuries ago.
I don't believe that God will allow those apostate denominations which in effect deny the divinity of His Son and preach a social gospel of redemption through good works and political activism to continue teaching and preaching their unbiblical works gospel indefinitely. If you are a true believer in Jesus Christ and the biblical doctrines of His first century Church you should get out of your apostate denominational church and discover what it feels like to know that you are in fellowship with your brothers and sisters of like faith in Christ. I recommend a good independent Baptist church like the one I belong to, but there are many other non-denominational independent churches just as good that don't bear the stigma that the media has managed to attach to the name "Baptist".
I have a conservative relative that attends a UCC, even though they are going to leave. I wonder if they were in church yesterday?
I think you are saying that my salvation depends upon the church I belong to. Otherwise, why in the world would yuo suggest that I should leave my current church (where the Gospel of salvation by grace through faith in Jesus is both taught and preached) and join another church?
Perhaps you know of the parable of the wheat and the tares? I believe that in some denominations (including my own), there are wheats alongside the tares.
And I also believe that it is God who saves -- an act of grace. God looks at the heart of each believer. I do not believe that God will condemn an inidivual simply because he or she is a member of a church that belong is in a denomination that is a member of the NCC.
