Pilgrimages to the Society of St Paul on Staten Island, N.Y. during the Pauline Year are now indulgenced since the rededication of the St Paul Statue on their grounds (see recent blog post). What is an indulgence? Visit this page from the United States Catholic Conference:
"The saints, the members of the Church who have arrived at perfect union with Christ, join their wills to the will of God in praying for those in the Church who are still on their pilgrimage of faith."
A number of popular devotions have indulgences attached to them. Indeed, the fact that a particular devotion has an indulgence attached to it is an indication that this devotional practice has proven itself within the Church to be helpful in bringing people closer to God. Because of the close association between popular devotions and indulgences, a clear understanding of the Church's teaching on indulgences is necessary to appreciate the role of popular devotional practices in the life of the Church.
