My brother Aaron titled this blog Dead Theologians, mainly as a place from which to discuss particular books we were reading by theologians. The criteria they must meet if we were to read them: They must be dead. This was our quote to justify this:
"I have lived nearly sixty years with myself and my own century and am not so enamoured of either as to desire no glimpse of a world beyond them." - C.S. Lewis
