Is your church a voluntary association, or a community in covenant? A voluntary association allows members to set their own rules for participation. A community in covenant is one in which the institution of the church sets the standards. This is a VAST contrast in approaches.
Many churches claim to be covenanted communities, but they really aren't. They function like voluntary associations. The more theologically liberal, the more likely this is the case. If your church is a voluntary association, chances are good that what your church is today is what it will be forevermore. It will only attract people who desire a low expectation environment.
