The Apostle Peter witnesses the ascension of Jesus of Nazareth on the Mount of Olives, receives the eight 'Books of Mystery' (the 'Keys to the Kingdom'), beholds the appearance of the holy Mother of God, and resolves to preach the Gospel to the ends of the earth.

After witnessing the ascension, and experiencing the miracle of Pentecost, Peter agrees to safeguard the books of divine mysteries, and prepares to start preaching the Gospel in Judaea.

Thirty years later in Rome, Peter and Clement create a compendium of books documenting the evangelization efforts of all the disciples on missionary travels. They add the eight books of mysteries that Peter received at the Ascension and create a repository of Faith, that is then archived in a great chest called the 'Ark of the New Covenant'.
