 The substance of "De Servorum Dei beatifιcatione et de Beatorum canonizatione" was incorporated into the "Codex Iuris Canonici" ("Code of Canon Law") of 1917, which governed until the promulgation of the revised "Codex Iuris Canonici" in 1983 by Pope John Paul II.Prior to promulgation of the revised "Codex" in 1983, Pope St. Paul VI initiated a simplification of the procedures.The Apostolic constitution "Divinus Perfectionis Magister" of Pope John Paul II of 25 January 1983 and the norms issued by the Congregation for the Causes of Saints on 7 February 1983 to implement the constitution in dioceses, continued the simplification of the process initiated by Pope Paul VI.
