“Flower Communion Sunday” – This Sunday’s service – “In the springing of the year” (Robert Frost) – will center around a flower communion ritual. This is a ritual introduced 100 years ago – June 4, 1923 – by the Rev. Norbert Capek to the Unitarian congregation he served in Prague of the then-Czechoslovak Republic. Some years later, the simple service that Capek created found its way to Unitarian congregations in the United States, where many Unitarian Universalist currently observe some version of it.
