It would have to be through the side door because it isn't in the front door, ie the bible.
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. 19 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 upon earth, it shall be loosed also in heaven.
*Feel free to post Holy Writ where Jesus established the New Testament Texts as the sole rule of Faith, OR, where He told His Apotles- "Look, ya better write this down, Capiche?"
