The Eucharist is the centre and origin of the life of the Church. All Eucharistic devotion is related to the Sacrifice of the Mass which perpetuates the Lord’s saving death and resurrection in the Memorial of the last supper in anticipation of the messianic banquet.
The Blessed Sacrament is normally reserved in a locked tabernacle. On special occasions the Blessed Sacrament is exposed for a short period of time (Holy Hour) to stimulate the faithful to an awareness of the presence of Christ and is an invitation to enter into spiritual communion with him.
The ordinary minister for exposition of the Eucharist is a priest or deacon.
Typically a monstrance is used to hold and clearly display the Blessed Sacrament on the altar. This allows the faithful to focus on, and devote themselves attentively in prayer to the Lord Jesus.
When the monstrance is used, there are 4 – 6 candles lit and incense is used.
There are brief songs, readings and exhortations which help lead to a better understanding of the Eucharistic mystery. There is a period of silence (normally 40 minutes) for personal prayer and reflection.
Towards the end of the Holy Hour there is the Benediction; the priest or deacon, wearing a humeral veil, blesses the people, using the monstrance that contains the Blessed Sacrament.
At the end of the period of adoration, the Blessed Sacrament is reposed in the tabernacle.
