"So Philip arranged a meeting of both sides at his Marburg castle in 1529 to attempt some kind of agreement on the eucharist. Everyone apart from Luther wanted a compromise, but he managed to wreck it. When told that Christ's human body could not be on earth and in heaven at the same time, he insisted, 'I do not want to hear reason... God is above all mathematics.' 'If he ordered me to eat manure, I would do it.'"
