From a reader…
Do all indulgenced works (eg visiting the Bl Sacrament for 30 mins) carry with them the three usual requirements (Communion, Confession & prayer for the Pope’s intentions)?
In the Norms for gaining indulgences in the Enchiridion Indulgentiarum we read that (my emphases):
23 a. Beside the exclusion of all attachment to sin, even venial sin, the requirements for gaining a plenary indulgence are the performance of the indulgenced work and fulfillment of three conditions: sacramental confession, eucharistic communion, and prayer for the pope’s intentions.
b. Several ?plenary? indulgences may be gained on the basis of a single sacramental confession; only one may be gained, however, on the basis of a single Eucharistic communion and prayer for the pope’s intentions.
c. The three conditions may be carried out several days preceding or following performance of the prescribed work. But it is more fitting that the communion and the prayer for the pope’s intentions take place on the day the work is performed.
d. If a person is not fully disposed or if the prescribed work and the three mentioned conditions are not fulfilled, the indulgence will only be partial; the prescriptions in N. 27 and N. 28 for those impeded are exceptions.
e. The condition requiring prayer for the pope’s intentions is satisfied by reciting once the Our Father and Hail Mary for his intentions; nevertheless all the faithful have the option of reciting any other prayer suited to their own piety and devotion.
I hope that helps.
