“And Simon Peter answered and said, Thou art the Christ, the Son of the living God.
“And Jesus answered and said unto him, Blessed art thou, Simon Bar-Jonah: for flesh and blood hath not revealed it unto thee, but my (Πατρος – Patros) Father (Πτα – Ptah) which is in heaven.
“And I say also unto thee, That thou art (Πέτρος – Petros) Peter, and upon this (Πέτρα – Petra) rock I will build my church; and the gates of hell shall not prevail against it. And I will give unto thee the (κλείς – kleis) keys of (Malkuth) the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven.” – Matthew 16: 16-19
