Seems like it would be appropriate at times for a congregation to hold a service of corporate confession. Are there not moments when a whole congregation is guilty, of failure to evangelize, of failure to remove sin from its midst, of squandering its resources on self, of going beyond what is written? This might be good after the supervisors have shown through teaching and admonition the error that has been committed. We see Israel doing it at times. Is not this expression of repentance what the Lord required of a whole congregation in Revelation?
