I've been looking at some small group covenants today. My guess is that most small groups today do not covenant together ( even though the covenant is a very scriptural idea ). Covenenting is like setting the ground rules. It tells people up front that you are taking this group seriously and that the only way you will achieve biblical community is if everyone 'agrees' to adhere to the covenant. In a group without a covenant there is less accountability and less buy in/commitment to the other members of the group.
Google 'small group covenants' and you will get a smattering of resources that you could adapt to your situation. Usually a covenant will cover the logistics ( when, where, how often ), the disciplines ( attendance, safety, accountability, confidentiality, responsibility, etc ), and the purpose of the group. People sign the covenant and turn it in to the group leader. I think it would also be a good idea for each group member to receive a copy of the covenant they have signed.
What do you think about covenants? Do you use them? Should you?
