[Strike Witch]

Jesus, and a lot of other biblical figures, are actually one individual, an alien with a messiah complex. The Ark of the Covenant was the ship's escape pod with a built-in defense system. Judas was the only other surviving alien of the ship's crash-landing, the captain who wanted to end his crazy crewman's dreams of interfering with the native planet. The Spear of Destiny is a modified alien weapon which was the only thing capable of killing Jesus, Judas was the one who instigated it. Of course, he still failed, and wrote down his account of events in a book in his native language. This book is the Voynich Manuscript.
