TRINITY SUNDAY

While Trinity Sunday is observed across various Western Christian denominations, it has a foundational connection to England and the roots of the Anglican Communion:

In 1162, Thomas Becket was consecrated as the Archbishop of Canterbury on the Sunday after Pentecost. His very first official act was to mandate an annual feast day dedicated to the Holy and Undivided Trinity on that specific date.

 After Becket was martyred in 1170 and canonized, his popularity soared throughout Europe. His local liturgical practice of observing Trinity Sunday spread across the Latin Church, eventually becoming mandated for all Christians in 1334.

Following his assassination, Becket’s remains were moved in 1220 to the Trinity Chapel at Canterbury Cathedral.
