C.S. Lewis’s “The Lion‚ the Witch‚ and the Wardrobe” can be seen as a spiritual allegory. The entire book has either subtle or somewhat blatant references to Christianity‚ and other religions. With references to Christ’s crucifixion and resurrection‚ Adam and Eve; it is pretty clear that Lewis intended his novel to parallel with Christian themes. But also having some elements of Paganism‚ Lewis portrays elements of the natural world and respecting it‚ much like how in the Pagan religion is about

In C.S Lewis’s celebrated book Mere Christianity he writes the following: “I am trying here to prevent anyone from saying the really foolish thing that people often say about Him: ’I’m ready to accept Jesus as a great moral teacher‚ but I don’t accept his claim to be God.’ That is the one thing we must not say. A man who was merely a man and said the sort of things Jesus said would not be a great moral teacher. He would either be a lunatic—on a level with a man who says he is a poached egg or else

Humanity is in danger of dying. According to C.S. Lewis‚ this humanity is not simply the existence as a biological species‚ but is instead founded upon the capacity to understand the objective values of the world. So‚ as the traditional values of the world are shunned‚ as they die‚ humanity will die as well. In Lewis’s book‚ The Abolition of Man‚ the permeation of moral relativism into the minds of the youth is the threat to humanity. In order to defend the importance of the doctrine of objective
