"Some people when they say that a thing is meant 'metaphorically' conclude from this that it is hardly meant at all. They rightly think that Christ spoke metaphorically when he told us to carry the cross: they wrongly conclude that carrying the cross means nothing more than leading a respectable life and subscribing moderately to charities."- C. S. Lewis
