Amos 5:15: Hate the evil, and love the good, and establish judgment in the gate: it may be that the Lord God of hosts will be gracious unto the remnant of Joseph.
Many would imagine that this gate is the physical door of the church, causing the confusion of evangelization in the church. Therefore, some took the alternate road of denying such gate of judgment at all, causing troubles they admit not to be the cause of.
Therefore, when I argue with those on whether non-Christians should serve in the Church, I realized we differ in the understanding of this "gate".
