The chant of the Passion of the Lord according to St. Matthew on Sunday in Ramis Palmarum at the Abbey of Our Lady of Gethsemani, Kentucky. The abbey belongs to the Order of Cistercians of the Strict Observance. The monks are listening to the chant of the Passion standing in the choir and facing the apse of the church with blessed palms in their hands. The priest is reading the Passion on the Epistle side of the altar, accompanied by the assistants who are wearing only albs and maniples, and a stole in the case of the deacon. This monastery, which is the mother of all other Trappist congregations in the United States, was founded on December 21, 1848, and was elevated to the rank of an abbey three years later. It is the oldest still operating monastery in the USA.
