Jack Of Hearts (1993)

Calvinism. Catholicism. Buckets of Blood.

A reclusive seeker-of-immortality scientifically keeps his body youthful, but is not able to control the devastating effects of aging on his mind. He wanders about his creaky estate; quoting scripture, taking mind-altering drugs, engaging in bizarre rituals and vaguely interacting with his dysfunctional family...until, of course, the inevitable blood-soaked climax.
