The story of Jesus giving Peter the keys to the Kingdom of Heaven is an important one in Christian theology. In the Gospel of Matthew, Jesus tells Peter, "And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven."
This passage is often interpreted as giving Peter and the apostles the authority to lead the church and make decisions regarding matters of faith and practice.
