Jesus said He was returning to a church without spot or wrinkle. I believe Him. Jesus said, His sheep know His voice. I believe Him. Jesus said, The gates of hell will not prevail against His church. I believe Him.
If your denomination or your denomination's culture is premenient in your life; if your denomination has replaced the Holy Spirit and Word of God in your life - then you are missing it and you are not seeing your brothers and sisters in Christ.

The Lord's prayers says, ..."thy will be done on earth as it is in heaven." When we get to heaven, there will not be separate Orthodox, Roman and Protestant camps. We will be one in Christ. We are NOW one in Christ. Let us be so.
We are supposed to be one in Christ now, but we are not now, nor do we appear to want to be all that much.
