“Simon Peter replied, You are the Christ, the Son of the living God. Then Jesus answered him, Blessed (happy, fortunate, and to be envied) are you, Simon Bar-Jonah. For flesh and blood [men] have not revealed this to you, but My Father Who is in heaven. And I tell you, you are Peter [Greek, Petros–a large piece of rock], and on this rock [Greek, petra–a huge rock like Gibraltar] I will build My church, and the gates of Hades (the powers of the infernal region) shall not overpower it [or be strong to its detriment or hold out against it]. I will give you the keys of the kingdom of heaven; and whatever you bind (declare to be improper and unlawful) on earth must be what is already bound in heaven; and whatever you loose (declare lawful) on earth must be what is already loosed in heaven. [Isa. 22:22.]”
