The bible says we're to love all men, especially the brotherhood. I think if the church was kinder to its own, the world would be more drawn to the church. No different than any other family. If you see love for one another in it, you're drawn to it. If members of the family love an outsider more than themselves, it doesn't seem right.
Which "church" are you speaking of? The Pentecostals, the SDA's, the Baptists, the Presbyterians, the Methodists, the Catholics, the Chuch of Christ denom...??
They can't all be right. They aren't all in union or unity. So if you are addressing an entity, which one?
