“The Souls in Purgatory, can pray for those, who address to them their petitions, and obtain from God help, forgiveness, assistance against temptations, and, all favors, both temporal and spiritual, which they may need.”  St. Robert Bellarmine  (Quoted by Rev. J. F. Durin, in his work “Novena for the Relief of the Poor Souls in Purgatory”, Nihil Obstat and Imprimatur Jan 1931)
