The Book of the Messiah Abridged edition

Two thousand years ago, two-time travellers are involved in a tavern brawl, resulting in one free room at the inn. It is all downhill from there. Fighting the zombie apocalypse in AD 27 while searching for a cure on Noah's ark, two friends embark on a mission to put their world right once more. Using their advanced technology in order to perform miracles and an abridged online copy of the Bible, they endeavour to recreate Christianity, becoming involved along the way in a revolutionary war to over throw a corrupt monarchy.
