The second lesson is from the Epistle to the Philippians with the passage so familiar from the Triduum and the third lesson from the Epistle to the Colossians. In the second nocturn the antiphon Felix ille triumphus etc is sung, the lessons relate the work of St. Helena in fourth century Jerusalem finding three crosses buried in a cistern. Not knowing which cross the LORD had died on each was placed on a woman with a sickness by Macarius, Bishop of Jerusalem. When touched by the True Cross the sick woman was instantly restored to health. In the third nocturn the psalms are sung under the antiphon Adoramus te Christe etc, the lessons are from a homily of St. Augustine on the Gospel of St. John. The ninth lesson is of the commemorated feast of SS Alexander, Eventius, Theodulus & Juvenal.
