1. The canonical norms concerning the procedure to be followed in the Causes of Saints are stated in the Apostolic Constitution Divinus Perfectionis Magister promulgated by John Paul II on 25 January 1983 (AAS LXXV, 1983, 349-355).

2. To initiate a Cause it is necessary that at least five years pass after the death of the candidate. This is to allow for greater balance and objectivity in the evaluation of the case and to allow the emotions of the moment to decant. There must be a clear conviction among people about his/her sanctity (fama sanctitas) and about the efficacy of his/her intercession with the Lord (fama signorum).
