vested in a humeral veil, holding a monstrance containing the Blessed Sacrament. friary in Ghent, Belgium Benediction of the Blessed Sacrament, also called Benediction with the Blessed Sacrament or the Rite of Eucharistic Exposition and Benediction, is a devotional ceremony, celebrated especially in the Roman Catholic Church, but also in some other Christian traditions such as Anglo-Catholicism, whereby a bishop, priest, or a deacon blesses the congregation with the Eucharist at the end of a period of adoration.
Exposition before the blessing
The actual benediction or blessing follows exposition of the Blessed Sacrament, i.e., the placing of the consecratedHost in a monstrance set upon the altar or at least exposition of a ciborium containing the Blessed Sacrament. Thus "the blessing with the Eucharist is preceded by a reasonable time for readings of the word of God, songs, prayers, and a period for silent prayer", while "exposition merely for the purpose of giving benediction is prohibited". The readings, songs and prayers are meant to direct attention to worship of Christ in the Eucharist. A prayerful spirit is encouraged also by periods of silence and by a homily or brief exhortations aimed at developing a better understanding of the mystery of the Eucharist. Latin hymns traditionally sung during the exposition are "O Salutaris Hostia", "Tantum Ergo", "Laudate Dominum" and "Ave verum corpus". The Divine Praises are a prayer traditionally recited but no specific hymn or prayer is required, except that, immediately before the blessing, one or other of seven prayers given in the Rite of Eucharistic Exposition and Benediction, 98 and 224-229 is to be recited.
Before publication of the 1973 Rite of Eucharistic Exposition and Benediction, there was no codification of the rite. However, the guidelines for the Diocese of Rome issued under Pope Clement XII and drawn up by the Cardinal Vicar, Prospero Lambertini, were widely adopted. The rite now in force for the Latin Church requires the use of incenseat the beginning of the exposition and before the blessing, if the Blessed Sacrament is exposed in a monstrance, but not if a ciborium is used. Similarly, the priest or deacon, wearing an alb or a surplice, should also put on a cope and use a humeral veil when giving the blessing with the Blessed Sacrament in a monstrance, but the cope is not required when using a ciborium. A person other than a priest or deacon authorized to expose the Eucharist for adoration cannot give the blessing with it. Immediately after the benediction, the Blessed Sacrament is replaced in the church tabernacle, while an acclamation such as "O sacrament most holy" is sung. Zucchetti are to be removed during the Benediction - they may only be donned again once the Blessed Sacrament is replaced.
