I've Had to Go Through This a Couple of Times.

The removing the one from among you is not a sin issue, or else we'd all just shut down the church doors and call it good. The reason it's done is actually to bring the person to repentance and to maintain the unity of the church. But could there be times where something like this is warranted? Yes,. If somebody is actively abusing children, for example, or harming members of the congregation, then yes, it may be necessary to remove them from among the congrega.
