SUNDAY MAY 27: A central and unfathomable mystery of the Christian faith takes center stage today, on the feast of Trinity Sunday. (Note: Trinity Sunday falls the first Sunday after Pentecost in the Western Christian Church each year, and on Pentecost Sunday in the Eastern Orthodox Christian Church.) White shines from the décor and vestments of most Western churches, as the faithful ponder the one God that is three Persons: the Father, the Son and the Holy Spirit. For many centuries, Christian leaders have taught that this mysterious truth must be believed by true followers of the faith.

Though the Holy Trinity is honored every Sunday, this day was officially introduced in the ninth century to focus on this particular doctrine.

For Christians, a joyous Gospel passage proclaims that God’s nature has been revealed: “Going therefore, teach ye all nations, baptizing them in the Name of the Father and of the Son and of the Holy Ghost.” The sacrament of holy communion still is celebrated in the name of the Holy Trinity. Believers hold that all members of the Blessed Trinity are equal, uncreated and infinite.

It’s said that no mortal can truly grasp the concept of the Holy Trinity, but efforts can be made! Try picking a shamrock today, or a viola tricolor; light a candle with three flames; or decorate a home altar with symbols of the Trinity. (CatholicCulture.org has more ideas. And, if you’d like to learn more about the viola tricolor, visit the American Violet Society’s page for this delightful little blossom.

SUNDAY, MAY 22: It’s been one week since Pentecost, and for Western Christians, this marks Trinity Sunday. A celebration of the Christian doctrine of the Trinity—the Father, the Son and the Holy Spirit—Trinity Sunday is celebrated across Western liturgical churches. Though the early Church observed no specific day for the Holy Trinity, Thomas Becket (1118-70 CE) helped spread the observance of such a day across Western Christendom when he said that the day of his consecration would be held as a new festival for the Holy Trinity. Still, a day set aside solely for the Holy Trinity continued to vary by Sunday in several regions until Pope John XXII accepted the festival into the official calendar of the Western Church, in 1334 CE.

Note: The Thursday following Trinity Sunday is observed as the Feast of Corpus Christi. In some countries, this feast may be moved to the following Sunday.

According to Christian tradition: Following the Ascension of Jesus and Pentecost, Christians regard that the Holy Trinity has been fully revealed. Last week, signs of the Holy Spirit were evident in red banners, roses and doves; this week, vestments are white and a new season begins. The shamrock and viola tricolor pansy symbolize the Trinity, and in some churches, the Athanasian Creed is recited or read.

ACTIVITIES & MORE

Families, youth groups and others can teach St. Augustine’s simplified explanation of the Trinity to children today. Children can also go outdoors to search for shamrocks and pansies, or prepare a dinner with cloverleaf rolls and a three-in-one fruit salad. The table may be decorated with a “Trinity” candle, and a vase of collected tri-petal wildflowers.
