Canonization process used for beatified who already have a cultus
Through an equivalent canonization or equipollent canonization (Latin: equipollens canonizatio) a pope can choose to relinquish the judicial processes, formal attribution of miracles, and scientific examinations that are typically involved in the canonization of a saint. This can take place when the saint has been venerated since ancient times and continuously by the faithful.
History
The veneration of martyrs and other saints is attested from the first centuries of the Church. However, canonization as an ecclesiastical procedure was not outlined until the 11th century with the aim of seeking to define those Christians who would deserve the universal reverence of the Church, thus avoiding confusion between local churches and seeking that the virtues of the deceased were fully proven. Already during this time the authority of the pope was appealed to claim to him or to the synods the power to determine said cult.[1]
In the 17th century, Urban VIII began to make pontifical declarations of canonization through papal bulls, the first canonized saints being Philip Neri, Ignatius of Loyola, Francis Xavier, and in other bulls Urban would decree the beatification of other Servants of God. Similarly, in 1634, through the bull Caelestis Hierusalem cives, he established such powers of beatification and canonization as exclusive to the Holy See.[2]
In the first half of the 18th century, Bishop Prospero Lambertini, before being elected as pope under the name of Benedict XIV, published his maximum liturgical work entitled De servorum Dei beatificatione et de beatorum canonizatione, where he expounded the procedure of equivalent canonization and described the possibility of establishing public veneration for a person whose reputation for holiness and heroic virtue has long been proven by tradition and for whom there was already a prior veneration in the Church.
This has been reiterated since then by various pontiffs up to modernity without the most recent provisions regarding the canonization process having repealed it as a valid practice, exclusive to the pope.
