KH-Cloudy, he is not talking literally but in a symbolic sense. Anyways, eventhough it was created by Japanese it would not limit them from putting symbollic characters in it. Anyways like already said. There are no Chrisitian specific symbols in KH. The general symbols can be applied to many systems and is not only inherent to Chrisitianity. Good versus Evil, Order versus Chaos, are all old themes that date defore Christianity.
