The application offers recordings of the Joyful, Painful and Glorious Mysteries of the Holy Rosary for souls in purgatory.
The Church ... recognizing very well the communion of the whole mystical body of Jesus Christ, from the earliest times of the Christian religion has cultivated the memory of the dead with great piety and, since "holy and healthy is the thought of praying for the dead so that they may be absolved of sins "(2 Mac 12:46), he also offered his suffrages for them". Our prayer for them can not only help them, but also make their intercession effective in our favor.
From the earliest times, the Church has honored the memory of the dead and has offered for them suffrages, in particular the Eucharistic sacrifice, so that, purified, they can reach the beatific vision of God. The Church also recommends alms, indulgences and works of penance in favor of the dead.
