The church is full of “Christians” who take this Jefferson Bible approach to the Word of God. They choose to rationalize and ignore scriptures they do not like, and walk in sin. What is sad, is that since they are church members and/or have leadership roles, they are completely deceived into believing they are doing God’s will.
Matthew 18:15-17 says how to deal with such people. I left a church due to a leader not being held accountable for sin, and I got “rebuked” for it.
There are legions of unbelievers in leadership roles.
