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.
Did Jesus Build the Church on Peter?
Peter's confession that Jesus is the Christ is the rock Jesus builds on. The builder is Jesus, the assembly is his, and the truth confessed is the foundation.
