The following is an excerpt from a sermon of St. Leo the Great, who’s Feast Day we celebrate today. In this excerpt, St. Leo gives us a little better understanding of our role in the Priesthood which was bestowed upon us at our Baptism.
“Although the universal Church of God is constituted of distinct orders of members, still, in spite of the many parts of its holy body, the Church subsists as an integral whole, just as the Apostle says: We are all one in Christ. No difference in office is so great that anyone can be separated, through lowliness, from the head. In the unity of faith and baptism, therefore, our community is undivided. There is a common dignity, as the apostle Peter says in these words: And you are built up as living stones into spiritual houses, a holy priesthood, offering spiritual sacrifices which are acceptable to God through Jesus Christ. And again: But you are a chosen people, a royal priesthood, a holy nation, a people of election.
For all, regenerated in Christ, are made kings by the sign of the cross; they are consecrated priests by the oil of the Holy Spirit, so that beyond the special service of our ministry as priests, all spiritual and mature Christians know that they are a royal race and are sharers in the office of the priesthood. For what is more king-like than to find yourself ruler over your body after having surrendered your soul to God? And what is more priestly than to promise the Lord a pure conscience and to offer him in love unblemished victims on the altar of one’s heart?”
– St. Leo the Great, 400-461, Doctor of the Church.
