Bishop Barron’s Sunday Sermons - Catholic Preaching and Homilies

The Church comes from the Eucharist for it is the sacrifice that makes saints. The Eucharist is essentially the fullest act of gratitude prefigured in Melchizedek finding its fulfillment in the sacrifice of Christ. Every Mass is a participation in and celebration of this sacrifice, but the feast of Corpus Christi is a time to be especially aware of the gift of the Eucharist.

Today the Church celebrates the Solemnity of The Most Holy Trinity. The Nicene Creed articulates the mystery of the Trinity with the wonderful phrase "begotten not made," meaning that the Son is not a creature but rather shares in the selfsame nature as the Father. The Holy Spirit is then the life-giving love breathed out between the Father and the Son.

Today we celebrate the great feast of Pentecost, one of the truly great moments in the life of the Church. The Holy Spirit comes to give many spiritual gifts, which prepare us to enter into relationship with Christ and embark on mission.

Too often we read the Ascension as the moment when Jesus “went away,” when he left us on our own and went off to heaven, where we hope some day to join him. But the Ascension is not Jesus going away; it is Jesus assuming his position as leader of the Church’s life.

The Church Catholic is a living thing; an organism rather than an organization. Therefore, it is continually moving, changing, adapting, reacting, answering new questions, and responding to new challenges. That's what we see in today's readings at Mass, which show us the Church in action in its very earliest days, not by itseld but in conjunction with the Holy Spirit.
