) is the congregation of the Roman Curia that oversees the complex process that leads to the canonization of saints, passing through the steps of a declaration of "heroic virtues" and beatification.After preparing a case, including the approval of miracles, the case is presented to the Pope, who decides whether or not to proceed with beatification or canonization. The congregation dealt both with regulating divine worship and the causes of saints.The new legislation establishes two procedural stages: the diocesan one and that of what is known as the Roman Congregation.
The veneration of confessors – of those, that is, who died peacefully after a life of heroic virtue – is not as ancient as that of the martyrs.
Only acceptance of the cultus by the pope made the cultus universal, because he alone ruled the universal Catholic Church.
Abuses, however, crept into this discipline, due as well to indiscretions of popular fervour as to the negligence of some bishops in inquiring into the lives of those whom they permitted to be honoured as saints.
Toward the end of the eleventh century the popes judged it necessary to restrict episcopal authority in this regard, and therefore decreed that the virtues and miracles of persons proposed for public veneration should be examined in councils, more specifically in general councils.
Popes Urban II, Calixtus II, and Eugene III conformed to this discipline.
