New Law Sacraments Are Efficacious Signs
- Catholic sacraments of the New Law differ from Old Testament rites because they cause the grace they signify.
- Aquinas treats the seven New Testament sacraments as efficacious signs that confer sanctifying grace, not merely symbolic acts.
Tripartite Structure Of Sacramental Causality
- Aquinas describes a tripartite sacramental structure: exterior sign, intermediate effect, and final effective grace.
- Stage two (res et sacramenta) mediates and signifies the final sanctifying effect (res tantum) achieved in stage three.
God Saves Us In A Concretely Bodily Way
- Sacraments are properly bodily and sensorial because God saves humans according to our physical nature.
- Using bread, wine, water, oil and gestures fits our embodied lives and can be beautiful and messy, requiring reverence (e.g., purifying vessels).
