A plenary indulgence is attached to the practice of the Way of the Cross. We state here the norms that govern it:
According to common custom, the pious exercise consists of fourteen devotional readings, to which some vocal prayers are added. To make the Way of the Cross, however, it is sufficient to meditate devoutly on the Lord’s passion and death, and therefore reflection on the particular mysteries of the individual stations is not necessary.
Progression from one station to the next is required. If the pious exercise is made publicly and moving from station to station by all participants is not possible without inconvenience, it is sufficient that at least the one conducting the Way of the Cross progress from station to station, while the others remain in their place.
Those legitimately impeded can acquire the same indulgence if they spend some time, e.g., at least a quarter of an hour, in reading and meditating on the passion and death of Our Lord Jesus Christ (see Manual of Indulgences: Norms and Grants, Apostolic Penitentiary. Translated into English from the fourth edition (1999) of Enchiridion Indulgentiarum: Normae et Concessiones, USCCB, Washington, D.C.).
