Sacramental Causality: “Effecting What They Figure!”

Preview

Circumcision and new-law sacraments were held to be efficacious signs of spiritual benefits in suitable receivers and/or the real presence of the Body and Blood of Christ. Since the material stuffs are not naturally endowed with the relevant causal powers, explanations are required for how they can be efficacious in the production of such effects. This chapter examines Aquinas' appeal to instrumental causality to explain how material rites do have relevant powers by participating in the causal efficacy of the principal agent (equals God). Then it considers Scotus' efforts to promote new-law sacraments as powerless causes connected with the effect by ‘non-obvious’ essential dependence relations, as well as Ockham's related conceptualization of sacraments as causes sine quibus non.
