"You will be years in space. The ship will be your monastery. After the patriarchal see is established at the Centaurus Colony, you will establish there a mother house of the Visitationist Friars of the Order of Saint Leibowitz of Tycho. But the ship will remain in your hands, and the Memorabilia. If civilization, or a vestige of it, can maintain itself on Centaurus, you will send missions to the other colony worlds, and perhaps eventually to the colonies of their colonies. Wherever Man goes, you and your successors will go. And with you, the records and remembrances of four thousand years and more. Some of you, or those to come after you, will be mendicants and wanderers, teaching the chronicles of Earth and the canticles of the Crucified to the peoples and the cultures that may grow out of the colony groups. For some may forget. Some may be lost for a time from the Faith. Teach them, and receive into the Order those among them who are called. Pass on to them the continuity. Be for Man the memory of Earth and Origin. Remember this Earth. Never forget her, but- never come back." Zerchi’s voice went hoarse and low. "If you ever come back, you might meet the Archangel at the east end of Earth, guarding her passes with a sword of flame. I feel it. Space is your home hereafter. It’s a lonelier desert than ours. God bless you, and pray for us."
