Disruption
"They caught so many fish that their nets were beginning to break."
To do the same thing over and over and expect different results is unwise.
The culture of the Church needs to be disrupted by the truth, and we can reach the truth by uncomfortable debate. Synods, among other things, are for disruption.
This doesn't mean grumpy conversations, or factions, or politicking. But it does mean honesty, and courage, and speaking and listening well.
