"Today we keep the commemoration of all the deceased faithful. After the Church as the loving Mother of all strove to honor with worthy solemnity all her children who already enjoy themselves in heaven, she seeks to aid those souls who yet suffer in the place of purgation by her powerful intercession with the Lord and Bride of Christ, so that as speedily as possible they may joining the community of heaven's citizens."
From The Roman Martyrology
Prayer of St. Gertrude for the Holy Souls
Eternal Father, I offer Thee the most precious Blood of Thy Divine Son, Jesus, in union with the Masses said throughout the world today, for all the Holy Souls in Purgatory, for sinners everywhere, for sinners in the universal Church, those in my own home and in my family. Amen.
