June 15, 2025 Holy Trinity

Although we have returned to Ordinary Time during the week following Pentecost, it will still be a while before we celebrate a Sunday of Ordinary Time, because this month our Sundays are filled with other important feast days: the Solemnities of the Most Holy Trinity (June 15), Corpus Christi (June 22), and Saints Peter and Paul (June 29).

This weekend we celebrate Trinity Sunday: and while it might be tempting to think that Trinitarian theology can be very dry, complicated, and abstract, and therefore easy to wonder about how important this celebration really is, I would suggest that the Solemnity of the Most Holy Trinity celebrates the most central mystery of our Catholic faith.

And I say that because mystery isn’t just the Catholic word for “something that’s really hard to understand.” To say that the Trinity is a mystery means that it is something that we can only know because God Himself has revealed it to us. According to Catholic teaching, it is theoretically possible for us to know that God exists using only the power of our own human intellect. And it is possible to know certain attributes that God must have. However, to know that the one God who created us and loves us is a Trinity of persons – Father, Son, and Holy Spirit – is something that we can only know about God because Jesus Christ has revealed it to us.

I like to think of Trinity Sunday as our celebration of the fact that God loves us so much that He doesn’t settle for only letting us know that He exists, but that He wants us to know who He truly is: Father, Son, and Holy Spirit. Put another way, Trinity Sunday is our celebration of the fact that not only does God love us, but indeed “God is love” (1 John 4:8): the Father who Loves the Son, the Son who is Beloved of the Father, and the Holy Spirit who is the Love shared by the Father and the Son.
