Episode notes
Threefold Effect of the Eucharist
- The Eucharist has three proper effects: nourishment, sacrificial participation, and ecclesial unity because the sacrament signifies eating, sacrifice, and communion respectively.
- Aquinas insists the sacrament not only symbolizes but actually effects spiritual nourishment, application of Christ's passion, and the mystical unity of the Church.
Mass Applies Calvary's Fruits Through Divine Instrumentality
- The Eucharist communicates the fruits of Christ's Passion so the Mass can apply Calvary's effects to believers even though the historical event is past.
- Aquinas explains this works because Christ's human acts operate instrumentally by virtue of the Godhead, allowing past meritorious acts to have present efficacy.
Receive Communion While In A State Of Grace
- Do prepare for Communion by being in a state of grace since the Eucharist presupposes friendship with God and nourishes charity.
- Aquinas notes Communion sustains, increases, restores from venial sin, and gives spiritual delight and growth.
