Our was somewhere is the constitution. Not one leader could quote it. If your congregation adopts a mission statement, remember to keep it simple. The next step for us was to teach our mission to everyone in the congregation. Worship bulletins, banners, newsletters, sermons, Bible studies, name tags, bulleting boards, children's messages, and responsive readings help teach the mission.
Redundancy is the key.
If you want your congregation to know the mission, then talk about it, decision based on it, and make it visible in every form of communication. As new ministries emerge, interpret them in light of the mission statement. In order to structure for mission, not maintenance, we reorganized our governing structure around our mission statement. Welcome, Grow, Care. Each core team leader oversees the work of dozens of ministry teams.
