Christianity is not about denomination...it is about the Lord.
I applaud you. Many don’t understand the term “church.” It refers to the body of believers - not a denomination. Those are just titles over a door. There are many in good standing within the walls of these “churches” who have never had a born-again experience and believe that they are doing the Lord’s work.
Jesus said that many will say to him, Lord, Lord have we not done many wonderful works in your name? He will say to them- depart from me you workers of iniquity - I never knew you. This is a very sobering Scripture.
