We don't know much of what these two saints did after the Resurrection, but we do know they lived and eventually died for Christ as martyrs. The Apostles, with Saint Peter as their leader, laid a firm foundation so Christs Church could be built and remain solid. So while our one holy, Catholic and Apostolic Church may take its share of beatings, Jesus promised us that the gates of the netherworld shall not prevail against it.
In reflecting on these two great saints, along with the other apostles, I began to think about all the riches and treasures we have been given in the Catholic faith. Yes, we have Scripture, the Word of God itself, but we also have Sacred Tradition, along with and through which Scripture should be read and meditated upon. And above all else, we have Jesus Himself in the Holy Eucharist. He gives Himself to us, sparing nothing for Himself so that we may come to know and love Him now and in the life to come.
May the holy company of Apostles praise God and may we praise Him along with them.
