26 Thus, in order that these celebrations bear still more fruit, upon the instances of the Ministers General of the three Franciscan families of the First Order, we accord the following favors drawn from the treasury of the Holy Church: I. In all Churches wherein the Third Order is canonically erected, and wherein will be celebrated by a Triduum the solemnities of the Centenary in the year to run from April 16, next: the Tertiaries each day of the Triduum, the other Faithful once only, may gain a plenary indulgence from their sins. All the Faithful who, with contrite hearts, will visit the Blessed Sacrament in one of these churches may gain at each visit ( toties quoties ) an indulgence of seven years. II. All the altars of these churches will be deemed for those three days privileged altars; during the course of the Triduum every priest may celebrate there the Mass of St. Francis, following the rite of the Mass pro re gravi et simul publice de causa according to the general rubrics of the Roman Missal inserted in the last Vatican edition. III. All the priests who serve these churches may, during these same days, bless beads, medals, and other objects of piety, enrich them with Apostolic indulgences, and apply to beads the Crozier and Bridgettine indulgences. As pledge of Divine favors, and in testimony of Our paternal benevolence, We accord with all Our heart, to you, Venerable Brothers, and to all the members of the Third Order, the Apostolic Benediction.
