Through the generosity of the Ardovino family, the Oratory at the Priory was renovated and a Memorial Chapel was established in the memory of Anthony and Mildred Ardovino.

Under the joint chaplaincy of Old-Catholic and Anglican clergy, the Oratory celebrates the Holy Eucharist, administers the Sacraments (Mysteries) and provides spiritual care for the Priory and the members of the Order and the Confraternity.

Since the Old Catholic Church and the Anglican Communion agree that Baptism is the primary sacrament whereby one becomes a Christian and thus a member of the Church, the Body of Christ, all baptized Christians are welcome to receive the Sacraments.
