The Order of Corporate Reunion (OCR), officially the Christian, Ecumenical, and Fraternal Order of Corporate Reunion, is an ecumenical association of clergy and laity of Anglican origin. The OCR was founded by Frederick George Lee, Thomas Wimberley Mossman, and John Thomas Seccombe between 1874-1877 in London. Established as an Anglo-Papalist society to continue the work of the Association for the Promotion of the Unity of Christendom, its founders sought to restore an apostolic succession recognized by the Catholic Church through reordinations as a means for reunion.
