The Kingdom Keys

This article by Rodney Kleyn explains the doctrine of the keys of the kingdom from Lord's Day 31 of the Heidelberg Catechism, demonstrating how church elders exercise their authority through the preaching of the gospel and the practice of Christian discipline. The resource explores how the keys function to open and close the kingdom of heaven through both proclamation and the regulation of sacramental access, grounding church discipline in Christ's command and the church's pastoral responsibility.
