Founded through the munificence of The Most Rev. Dr. and Mrs. Craig J. N. de Paulo, St. Willibrord Priory is an Old-Catholic community of priests, oblates and associates dedicated to a life of contemplation, study and teaching. Most members of the Order are involved in higher education as scholars, professors, university administrators, writers and editors, providing the primary means by which the priory sustains itself.
An autonomous (sui iuris) priory of the Order of St. Willibrord, the priory has an Oratory (chapel), library, refectory, chapter room, common room, Chancery office, reception parlor, priory hall, gift shop and gardens in addition to the archbishop’s private apartment, sexton's quarters and enclosed dormitory for members and guests.
As the Generalate of the Order of St. Willibrord, the priory is governed by the Master General who is also Grand Prior of the priory. The Master General is assisted by his Curia, the Priory Chapter and the Board of Councillors.
The Priory estate consists of nearly two and a half acres, located within the Village of Angelica, now part of Mohnton, near to Nolde Forest, in Cumru Township, Berks County, Pennsylvania.
