A SABBATH PRESBYTERY
As Israel was constantly learning, being set apart by God was less a reason for pride than of humble awe. It isn't that God took a special people and rewarded them for their greatness. Scripture is very clear that God took a "no-people" and made them into "God's people." (1 Peter 2:10) I note that because it is a humbling, not a prideful thing to recall that we are God's people.
At a Presbytery meeting, ask the following three questions for spontaneous response from the floor. Have someone prepared to keep note of the responses for each of the three questions.
"What it means that their church has been called by God to be a witness in this larger world?"
Next, have them respond to that question about the call of clergy: "What does it mean to say that clergy of our presbytery are set apart by God for a special purpose?"
Third, respond to the question concerning elders. "What does it mean to say that elders of our presbytery are set apart by God for a special purpose?"
Assign a spokesperson to share the collected responses to each question at the appropriate time. Have a liturgist lead the gathered people in a litany in which they read the question followed by the gathered responses to that question. Then the whole body responds: "We are a chosen race, a royal priesthood, a holy nation, God's own people." At the end of the litany, have the body rise and sing the doxology.
What you are doing is taking a sabbath moment for people to recall who and whose they are. It is one small step in helping the church to not be absorbed into the culture but to remember who they are.
