Silverstream Priory was, at its conception, placed under patronage of the Blessed Virgin Mary, Our Lady of the Cenacle. The Cenacle is the upper room in which Our Divine Lord instituted the adorable Sacrament of His Most Holy Body and Blood, making His Apostles the first priests of the Church, and humbling Himself to wash their feet. In the splendour of His Resurrection, Our Lord appeared to His Apostles, again in the Cenacle. It was in the same Cenacle that the Apostles, assembled around the Virgin Mother of Jesus, awaited the promised Gift of the Holy Ghost, by persevering together in prayer. When, on the day of Pentecost, the Holy Ghost descended upon them in tongues of fire and in a mighty wind, this too took place in the Cenacle. Marked by this mystery of the Cenacle, the ecclesial mandate of the Benedictine Monks of Perpetual Adoration is to adore the Most Holy Sacrament of the Altar in a spirit of reparation, and to intercede for the sanctification of priests by “persevering with one mind in prayer with Mary, the Mother of Jesus” (Acts 1. 14).
