The custom of the Seven Sundays of Saint Joseph
Pope Gregory XVI, whose pontificate began in 1831, encouraged the custom of dedicating the seven Sundays before March 19 to Saint Joseph in memory of his seven sorrows and joys, and attached many indulgences to this devotion. His successor, Blessed Pope Pius IX, asked the faithful to petition Saint Joseph to alleviate the afflictions of the universal Church in those times.
