The Willibrord Society is an umbrella term for a group of national societies with the aim of promoting awareness and cooperation between Anglicans and Old Catholics. There are currently active Willibrord Societies in England, the Netherlands, Germany, Switzerland, Austria, Italy, the Czech Republic and the United States. The aim is achieved through publications, meetings, special events and church services, and common projects in such fields as liturgy, youth work, charity giving, encouraging representation at synods and other events.
The name recalls St Willibrord, the English missionary who acted as "Apostle to the Frisians," and was consecrated the first bishop of Utrecht in 695. Most national societies organize special events and services to coincide with St Willibrord's Day, 7 November.
The English Society of St Willibrord was founded in 1908 with the aim of fostering closer relations between the Church of England and the Old Catholic Church. Its activities were at first aimed at promoting full communion between the two churches, which came about in the Bonn Agreement of 1931.
