The Benedictine Monks of Perpetual Adoration of the Most Holy Sacrament of the Altar are a monastic family serving the Holy and Undivided Trinity under the sixth-century Rule of Saint Benedict.  They are established at Silverstream Priory in Stamullen, Co. Meath, Ireland, in the Roman Catholic Diocese of Meath.

Under the patronage of Our Lady of the Cenacle, the monks of Silverstream Priory devote themselves to the worthy celebration of the Sacred Liturgy (which St Benedict called the Opus Dei, or "Work of God"), in its age-old classical forms and to perpetual adoration of the Most Holy Sacrament of the Altar, the Eucharistic Face of Christ, in a spirit of reparation. Their life of praise and adoration is marked by a heartfelt solicitude for the sanctification of priests.

Without leaving the enclosure of the monastery, the monks undertake various works compatible with their vocation, notably hospitality to the clergy in need of a spiritual respite, and the operation of an excellent Catholic book shop located in the gatehouse of the priory.

In our canonical Decree of Erection (dated 31 December 2012), Dr Michael Smith, Bishop of Meath, writes concerning the monks of Silverstream:

The Benedictines of Silverstream Priory came to Ireland to take root among us, recalling in some way the Irish monks of old who, for the love of Christ, set out as pilgrims to plant new cloisters on foreign shores.

The real stability of a monk is both inward and ecclesial, insofar as it is fixed in the Sacred Host, that is, in Jesus Christ truly present as Priest and Victim upon the altars of the Church, whence He offers Himself to the Father as a pure oblation from the rising of the sun to its setting. Ubi Hostia, ibi Ecclesia.

The particular form of Benedictine life that has come, finally, to bury itself, take root and, by the grace of the Holy Spirit, flourish in the Diocese of Meath, is profoundly Eucharistic and ecclesial.

The influences that have come to bear upon its development are as many as they are rich, beginning with the final years of the pontificate of [Saint] John Paul II, marked by the Encyclical Ecclesia de Eucharistia, and by the indiction of the Year of the Eucharist in the Apostolic Letter Mane nobiscum Domine, and including the post-synodal Apostolic Exhortation of Pope Benedict XVI, Sacramentum Caritatis, in which the Holy Father expressed his “appreciation and support for all those Institutes of Consecrated Life whose members dedicate a significant amount of time to Eucharistic adoration.

Excerpts from our Constitutions

"The study of the Holy Rule will remain each monk’s lifelong pursuit, seeking in every age of the spiritual life to understand it better, to savour its wisdom, and to put it into practice 'with a dilated heart and with the unspeakable sweetness of love' (Holy Rule, Prologue)."

"The charism of Catherine–Mectilde de Bar (1614–1698), foundress of the Benedictines of Perpetual Adoration of the Most Holy Sacrament of the Altar and monastic reformer in the seventeenth century, expressed in the text of the Constitutions as she left them at the time of her death, and in her other writings, inspires and informs our harmonisation of the Benedictine tradition with a life of Eucharistic adoration and reparation."

"As members of a coenobium that is Eucharistic in its origin and finality, the monks will live from the altar and for the altar, spurning all things inimical to the Sacrament of Charity, and to the unity in the Holy Spirit that is its fruit. They will, moreover, strive to embrace, humbly and manfully, whatsoever deprivations, infirmities, and sufferings should be permitted by the Father as the means to a more perfect union with the Christus Passus, who, in the Most Holy Sacrament of the Altar remains forever the sacrificial Victim offered once from the Cross, the Hostia perpetua."

"We, then, honour the Mother of Jesus, who sustained the unanimous prayer of the Apostles in the Cenacle of Jerusalem, as the Regina Monachorum and heavenly Abbess under whose protection we desire to persevere in adoration of the Lamb who was slain."

"The silence of the Sacred Host must reign, then, not only over the hearts, minds, and lips of the monks, but over the entire monastery and its land, so as to foster an atmosphere of order and of peace conducive to the prayer of the heart in a spirit of ceaseless adoration."

"They will lift up their voices together with their hearts in the chant of the Church, observing with good cheer the discipline, restraint, and attention that it requires. Thus will they worthily echo here below the praise of the Angels that resounds ceaselessly in the courts of heaven."

"Ignored by great multitudes, denied by heretics, delivered over to sacrilege, and treated with coldness, irreverence, and indifference even by those of His own household, Jesus Christ seeks men to console Him in the Sacrament of His Love, by adoring Him in a spirit of reparation by day and by night. This, then, is the reason for the existence in the Church of monasteries wholly devoted to the reparation of the glory of the Divine Saviour who is, in this august mystery, as one emptied out."
