When the necessary legislation had been drawn up, the Pope then established for the Campos group, with effect from 18 January 2002, the Personal Apostolic Administration of Saint John Mary Vianney, with authority over those Catholics in the Diocese of Campos who wished to use the Roman Rite in the form it had before the revisions following the Second Vatican Council. On the date of entry into effect of the new arrangement, a ceremony was held in the Cathedral of Campos on Friday 18 January. The Papal Letter was presented to Bishop Rangel in the course of the celebration, by Cardinal Dario Castrillón Hoyos, President of the Pontifical Commission "Ecclesia Dei".
