As Patrick and Finnian were playing on Friday, we heard Finnian tell Patrick:
"Patrick, Jesus died on the cross for us, so that we can live with Him in Heaven. The devil can never go to Heaven because he is bad. The devil will never be allowed in Jesus' house."
Finnian must be listening to and/or understanding more of his siblings' religion lessons, our pastor's sermons, and the Sorrowful Mysteries of the Rosary, then I realized.
St. Michael, the Archangel, defend us in battle. Be our safeguard against the wickedness and snares of the devil. May God rebuke him, we humbly pray; and do thou, O Prince of the heavenly host, by the power of God, cast into hell Satan and all the evil spirits who prowl about the world seeking the ruin of souls.
