A lot of folk think that because some pagan religions use terms like "King of Kings" that Christianity has just copied the expression and therefore is just one more of many religions, no better and probably worse. Certainly it has no more validity than they do.
But consider. It could equally well be the other way round. After all, if the Christian Deity is the one true God, creator and master of all, that fact would resonate through all eternity. In other words, the pagans (who like all Humans have an instinctive link to their creator) are simply copying the term from Him!
I think the one and only CS Lewis (who was an Anglican incidentally) puts it a lot better than I do!
Very well put. Which of Lewis' books is that?
