And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.

And I will give to thee the keys of the kingdom of heaven. And whatsoever thou shalt bind upon earth, it shall be bound also in heaven: and whatsoever thou shalt loose on earth, it shall be loosed also in heaven.

Saint Matthew 16.18/19
