Scholion. On the Faculty of Blessing Things with the Application of Indulgences
I. One who has received the faculty of blessing crosses, medals, scapulars, rosaries, etc., with the application of indulgences, is not bound to exhibit it to the Ordinary unless this is expressed in the concession.1 One who has obtained the faculty of privately blessing pious things with the application of indulgences cannot use that faculty publicly, for example in a church or oratory before the faithful gathered there and holding in their hands the things to be blessed.2
II. As regards the form or rite to be observed in blessings, hold these things:
The ordinary or customary form - which is done by forming the cross over the thing to be blessed, without pronouncing any formula and without sprinkling holy water - suffices for crosses, medals, and rosaries, except, however, rosaries of the Most Holy Rosary and of the Seven Sorrows;3 it also suffices for crucifixes with a plenary indulgence at the point of death; likewise for the crucifix of the Way of the Cross in favor of the faithful who are impeded; and it always seems to suffice when no proper form is prescribed. In that case, the sign of the cross with the words "In the name of the Father and of the Son and of the Holy Spirit," together with the sprinkling of holy water over the object to which indulgences are to be attached, certainly suffices.4
The proper form must be used for rosaries of the Most Holy Rosary and of the Seven Sorrows, for crosses of the stations of the Way of the Cross, for a plenary indulgence at the point of death or the Apostolic Blessing, as it is called, for enrollment in the Confraternity of the sacred Scapular, etc.5
Cardinals, by canon 239, § 1, 5° and 6°, from their promotion enjoy the faculty of blessing everywhere, by the sign of the cross alone, with all the indulgences customarily granted by the Holy See, rosaries and other prayer-beads, crosses, medals, statues, and scapulars approved by the Apostolic See, and of imposing them without the burden of registration; likewise, by a single blessing, of erecting in churches and oratories, even private ones, and other pious places, stations of the Way of the Cross with all the indulgences which have been imparted to those performing such a pious exercise; and also of blessing for the faithful who, because of illness or another legitimate impediment, cannot visit the sacred stations of the Way of the Cross, Crucifix images with the application of all indulgences attached by the Roman Pontiffs to the devout exercise of the same Way of the Cross.
