[1] There are currently active Willibrord societies in the British Isles, 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 SSW in the British Isles currently supports the Anglican chaplaincy at Schiphol Airport in the Netherlands, in which Old Catholics are also involved.
The name recalls St. Willibrord, the Anglo-Saxon 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.
