Matthew 16:18: Who Builds the Church?
Jesus attaches his promise to build his assembly to Peter's confession that he is the Christ, the Son of the living God. That promise secures the church's endurance without guaranteeing that every congregation or denomination will flourish.
Matthew 16:18: One Assembly Jesus Will Build
Jesus does not count congregations in Matthew 16:18. He names one assembly he will build himself, on the rock of Peter's confession that he is the Christ, the Son of the living God.
