The Possession of the Church's Authority

Jim ButlerMatthew 18:18–20

Christ's declaration in Matthew 18:18 — 'whatever you bind on earth will be bound in heaven' — establishes that the local church possesses a real, though delegated, authority to exercise the keys of the kingdom through gospel preaching and church discipline. Drawing on the parallel passage in Matthew 16:19 and the Heidelberg Catechism's definition of the keys, the sermon argues that binding and loosing refer to the church's authority to exclude the unrepentant and restore the repentant, always in accordance with God's word and never by arbitrary preference. Verses 19 and 20 ground this authority in the corporate prayer and the promised presence of Christ himself among his people when they faithfully implement these keys. The sermon closes with a summons to love the church, exercise its authority prayerfully, and pursue its three primary duties — preaching, discipline, and the administration of the sacraments — without addition or subtraction.
