Praying for the Holy Souls in Purgatory was the special apostolate of the late Requiem Press. Every order included a free copy of our booklet "Daily Prayers for the Church Suffering". Do remember the holy souls today and all during November. A plenary indulgence is available for the holy souls by your prayers-praying for them at a cemetery during the next 9 days (under the usual conditions).
1 Out of the depths I cry to thee, O Lord; 2 Master, listen to my voice; let but thy ears be attentive to the voice that calls on thee for pardon. 3 If thou, Lord, wilt keep record of our iniquities, Master, who has strength to bear it? 4 Ah, but with thee there is forgiveness; be thy name ever revered. 5 I wait for the Lord, for his word of promise my soul waits; 6 patient my soul waits, as ever watchman that looked for the day. Patient as watchman at dawn, 7 for the Lord Israel waits, the Lord with whom there is mercy, with whom is abundant power to ransom. 8 He it is that will ransom Israel from all his iniquities. (Psalm 130)
Update: Attended Divine Liturgy at St. Peter's in Cheraw, SC for All Soul's Day. Father used black vestments-as is appropriate, and faced the tabernacle during the consecration (as is appropriate).
Oremus pro invicem!
