FIRST ARTICLE [III, Q. 62, Art. 1]
Whether the Sacraments Are the Cause of Grace?
Objection 1: It seems that the sacraments are not the cause of grace. For it seems that the same thing is not both sign and cause: since the nature of sign appears to be more in keeping with an effect. But a sacrament is a sign of grace. Therefore it is not its cause.
Obj. 2: Further, nothing corporeal can act on a spiritual thing: since "the agent is more excellent than the patient," as Augustine says (Gen. ad lit. xii). But the subject of grace is the human mind, which is something spiritual. Therefore the sacraments cannot cause grace.
