Actually, it is. Like I said, all sinners are welcome there would be no church otherwise. And there is no church that exists that includes people who do not sin. Ebdorsement of sin through weakening scripture, doctrine, and teaching is another thing altogether. My church requires that people conform themselves to what Jesus and the Bible teaches.
“My church requires that people conform themselves to what Jesus and the Bible teaches.”
Are you sure? Or should they conform to what your church teaches?
So, your all-inclusive statement was false. You don't include in the life of the church those who rebelliously refuse to conform themselves to what Jesus and the Bible teaches, or outright unbelievers.
If you did, I'd never darken the door of your "church." It wouldn't be any different from a UU club.
