The Mystery of the Holy Trinity

What is a mystery? We usually think of a mystery as something that can be solved through investigation and research—for example, a detective solving a crime. But the dictionary defines mystery as “something not understood or beyond understanding.”

Such is the case with our Catholic Faith. The mysteries of our faith are not things that can be solved, but rather truths that are beyond our limited human comprehension. They have no explanation but instead require faith to accept and believe. So put away your magnifying glass, Sherlock. That’s not going to work here.

One such mystery is the Holy Trinity, which we celebrate today on Trinity Sunday, the Sunday after Pentecost. The Trinity is something that Catholics have a basic understanding of—one God, three persons—but when it really comes down to it, it’s a confusing concept.

“I do not seek to understand in order that I may believe, but I believe in order that I may understand…if I did not believe, I would not understand.” — Anselm of Canterbury

It’s not something we can fully comprehend, but it’s a mystery we can dive a bit deeper into. So how does the Holy Trinity apply to our lives? Fr. James Kubicki, regular contributor to Morning Air, offered a message that we can take away from this Sunday’s celebration.

“God is this mystery of persons, this communion, and it’s not three alienated, separated persons in one, it’s a communion of love. And if you think about it, we’re made in the image and likeness of love. In other words, we’re made not to be at war with one another, not to hate one another, not to be at conflict with one another, but to be in communion of love with one another,” he explained.

Pope Benedict XVI often reminded us that the Church is not an institution but a communion. This Trinity Sunday, let’s consider how can we work to be in greater communion with our Church, our neighbors, our family, and all brothers and sisters in Christ.
