SUNDAY, JUNE 11: White banners are draped and vestments shine as a sign of purity as Western Christian churches worldwide celebrate Trinity Sunday. Note: In the Eastern Christian Church, Trinity Sunday is observed on the Sunday of Pentecost. A culmination of the Nativity, Epiphany, Resurrection, Ascension and Pentecost, Trinity Sunday calls to mind the role that each member of the Holy Trinity—the Father, Son and Holy Spirit—play in Christianity.
Many Christians are surprised to learn that the original writers of the New Testament did not use the term “Trinity” as it appears in mainline Christianity today. While the three elements of divinity, God and Christ and Holy Spirit, were a part of the faith from its early years, the famous theologian Tertullian (who lived and wrote in Africa) is widely credited as introducing the first full analysis of the Trinity in the early 3rd century. The doctrine wasn’t formalized among Christian leaders until the fourth century.
For centuries, church leaders argued that the Trinity was honored every Sunday. But, in the 12th century, Thomas Becket declared that the day of his consecration should be an annual festival in honor of the Holy Trinity. The observance spread through Western Christianity, and was placed in the general calendar in the 14th century.
There is, perhaps, nothing more central to the creed of the Christian faith—and yet, so elusive, in comprehension of it—than the Holy Trinity. Through the centuries, countless saints have attempted to teach about the Trinity. Among the most famous was a three-leaf clover that tradition says was used by St. Patrick.
CUSTOMS & THE ATHANASIAN CREED
On this one Sunday each year, many Christians around the world recite the Athanasian Creed (read it here). Some bake cloverleaf rolls to reflect the Trinity, or set the table with a centerpiece of triple-leaf flowers.
