The Holy Trinity

The Sunday after Pentecost came to be kept in the West as Trinity Sunday, although it was not prescribed as a universal feast until 1334. In a sense, every feast must be a festival of the Trinity, because the whole Trinity is at work in every moment of creation, redemption and sanctification; but Trinity Sunday provides a particular occasion to reflect on the revelation of God’s self as
Trinity, immediately after the Great Fifty Days of Easter. The numbering of the following Sundays ‘after Trinity’ continues the practice of The Book of Common Prayer.
