The Church offers us different prayers that we can say each day of the week for the faithful departed. These prayers are especially useful for offering a novena on behalf of the dead, or for praying during those seasons of the year (November, in the Western Church; Lent, in the Eastern Church) designated by the Church as times of fervent prayer for the dead.
Sunday: On Sunday, we offer our prayer for the souls in Purgatory through the Precious Blood of Christ. We remember especially the most forsaken soul in Purgatory—the one who has no one else to pray for him.
Monday: We offer our prayer again through the Precious Blood of Jesus, especially that shed during his scourging, and we remember in a special way today that soul which is closest to leaving Purgatory and entering into the Kingdom of Heaven.
Tuesday: Christ shed His Precious Blood for us when He was crowned with thorns, and we offer our prayer today through that Blood for the soul in Purgatory that is most in need of our prayers.
Wednesday: Today, we pray in a special way for that soul in Purgatory which has the greatest merit, and we offer our prayer through the Blood that Christ shed when He carried His Cross to Calvary.
Thursday: On Thursdays, we remember Christ's institution of the Sacrament of Holy Communion at the Last Supper on Holy Thursday, and so we offer our prayer today through the Body and Blood of Christ. We offer it especially for the soul in Purgatory most devoted to the Eucharist.
Friday: Christ died on the Cross on Good Friday, and our prayer today is offered through the Blood He shed on that day. We remember especially that soul for whom we have the greatest obligation to pray—someone we knew who has died and who is in need of our prayers.
Saturday: As our week of prayer for the faithful departed comes to a close, we offer our prayer today especially for that soul in Purgatory most devoted to Mary, the Mother of God, and we offer it through the Precious Blood that she saw flow from her Son when the spear was thrust into His side on the Cross.
