Once you've written your mission statement, establish a list of bylaws that'll govern your church. This list will serve as a sort of "rule book" that you and your members should follow.
Every church follows a list of bylaws. If you're not sure where to start, consider visiting other churches and asking them about theirs. You can also look up church bylaws online and modify them to your preferences.
Your bylaws should cover the following points:
How are decisions made in your church? Does it have to go through a series of hierarchies, or does it simply require a set number of votes? If so, how many votes are required to approve resolutions?
How are meetings conducted? In the same vein, how often should meetings be held? Who isn’t allowed in the meetings? How many members are required to officially conduct business, cast votes, etc.?
Responsibilities and Power
Legally, who's responsible for your church? Who's allowed to bind the church contractually? What are the obligations of each member of the church, alongside its board and management group?
Replacing Directors and Officers
What process does your church follow in terms of removing and replacing an empty seat?
What’s your church's membership process? How often do members have to participate and/or attend? How often do they have to contribute financially, if at all?
