hmmm i think you might be mistaken on this one; one of the difficulties facing "schizophrenics" is their sense of isolation, marked by a lack of loving relationships. it'd be hard to compare a diagnosed schizophrenic's relationship to jesus with that of a relatively well-adjusted humanoid's relationship with jesus: there are reasons a "schizophrenic" is classified as such.
Many of the medieval hermits were textbook definition of modern schizophrenics. They lived by themselves, ignored personal hygeiene, acted bizarrely and heard God talking to them constantly.
