All Souls Day, observed on November 2nd in the traditional Catholic view, is a solemn day dedicated to praying for the souls of the faithful departed who are believed to be undergoing purification in purgatory before entering heaven. The importance of this day lies in the Catholic belief in the Communion of Saints, which teaches that the living can assist the dead through prayers, almsgiving, and the offering of Masses. By commemorating All Souls Day, Catholics express love and solidarity with those who have passed away, emphasizing the hope of eternal life and the power of intercessory prayer to aid souls on their journey to God.
