Catholics celebrated Trinity Sunday -- the observance that follows Pentecost and that commemorates the Father, Son and Holy Spirit -- this past weekend.

“Happy Trinity Sunday! May the Triune God bless you, protect you and keep you forever,” Nick Chancey, campus minister and director at the Marshall Catholic Newman Center, tweeted on June 4.

The Feast of the Holy Trinity was observed by Western Christian Churches on Sunday. The celebration was established in 1334 by Pope John XXII. The occasion, which follows Pentecost by a week, serves as a chance to honor and pay tribute to the Father, Son and Holy Spirit, also called the Holy Trinity. Churches typically mark the occasion with special services and celebrations that focus on the divine unity and presence of the Holy Trinity, according to National World.

The Feast of the Holy Trinity presents a challenge when it comes to comprehension and explanation, as it revolves around a doctrine rather than a specific event. The doctrine of the Trinity stems from the belief that God is a singular entity that exists as three distinct persons: the Father, the Son and the Holy Spirit. It's important to note that the term "Trinity" itself does not appear in the Bible. The Trinity is often symbolized by a triangle with three interconnected rings, each representing one personage of the Trinity, according to Bible Gateway Blog.

Catholic leaders across the nation took the time to post on social media about the day.

"Friends, today we come to Trinity Sunday, which has been called “the preacher’s nightmare,” Bishop Robert Barron, of the Diocese of Winona-Rochester, tweeted on June 4. "But as you probably know from previous sermons of mine, I don’t agree with that at all. I think every Sunday is Trinity Sunday.” 

Churches often prepare various special activities to commemorate the occasion of Trinity Sunday. Events may include concerts, craft sessions for children, gatherings and other forms of celebration. Some people often used the occasion to consume foods that incorporate the theme of three to represent the Father, the Son and the Holy Spirit. Neapolitan ice cream or tricolor pasta are some examples of symbolic culinary choices, according to Twinkl. 

"This Sunday we are invited to contemplate the central mystery of our faith — that our loving God is one God in three persons," Los Angeles Archbishop Jose Gomez tweeted on June 4. "He is the Father, the Son and the Holy Spirit — a beautiful communion of three divine persons in love.”
