The Postgate Society is the official diocesan association to provide knowledge of Catholic History and to foster devotion to the martyrs and those who preserved the faith in penal times .
Members receive a regular newsletter.
The Society helps to sponsor the annual Catholic History Day in July. There is a monthly Mass for all members, living and dead. Membership of the Society is open to everyone. The Postgate Society is part of the Diocese of Middlesbrough, a registered charity . There were thus strong political, as well as religious, reasons to try to suppress Catholicism in England.
