lock the church doors

"Despite his insistence on the primacy of the church, Calvin knew the church had its limits. John Bunyan's Pilgrim's Progress illustrates these limits well. In his classic allegory, Bunyan calls the church "the house built by the Lord of the Hill for the safety and rest of pilgrims." ...Then Bunyan has the keepers of the house send him away, out into the world.

Calvin did the same for his parishioners by locking the church doors after the service...Calvin locked the church doors so the church could be in the world...because he wanted the church to be salt and light in the world that God made and entrusted to us."
