While one can develop strange beliefs in fields one knows little about, it does sound like he in particular may have been suffering from Schizophrenia. The inability to function, the depression you describe and (at the risk of courting trouble for criticizing religion) his report of visions and extreme religious convictions are pretty overwhelming indicators.
