Outside the Eucharistic celebration, the Church is careful to venerate the Blessed Sacrament, which must be reserved... as the spiritual center of the religious and parish community" (Paul VI, Mysterium fidei, n. 68).

What is Adoration of the Blessed Sacrament?
Eucharistic Adoration is the adoration of Jesus Christ present in the Holy Eucharist. In the many parishes and churches that have this devotional practice, the Holy Eucharist is displayed in a special holder called a monstrance, and people come to pray and worship Jesus continually throughout the day and often the night.

Christ’s great love for us was shown when he was crucified on the cross to pay the penalty for our sins and give us eternal life. He loves us without limit, and offers Himself to us in the Holy sacrament of the Eucharist. Can we not give Jesus a few minutes of love and adoration in return?

What is Exposition of the Blessed Sacrament?
The ceremony in which a priest or deacon removes the Sacred Host from the tabernacle and places it on the altar for adoration.

In public exposition the Sacred Host is placed in the lunette of the monstrance and elevated so that all adorers can see it. In private expositions the tabernacle door is opened and the ciborium containing consecrated Hosts is brought forward.

Any good cause is reason for private adoration. Public exposition of the Blessed Sacrament requires a period of adoration, in private or public with prescribed hymns and prayers, as well as the blessing with the monstrance.

Definite days for public adoration of the Blessed Sacrament are no longer specified for the universal Church; now any days may be chosen for good reasons; and for regular exposition permissions are granted by the local ordinary. The ceremony was introduced in the fourteenth century under the influence of the newly established feast of Corpus Christi.

Some religious monasteries and convents with special permission have the Sacred Host perpetually exposed for special honor and devotion with someone in attendance night and day. (Pocket Catholic Dictionary, by John A. Hardon, S.J.)

What is a Holy Hour?
A pious devotional exercise consisting of mental and vocal prayer with exposition of the Blessed Sacrament. It draws its inspiration from Christ's words to the Apostles in Gethsemane: "Can you not watch one hour with me?"

It was taught by the Savior to St. Margaret Mary (1647-1690) as one of the special practices of the Sacred Heart devotion. In the early nineteenth century a confraternity was founded at Paray-le-Monial, France, to spread the devotion, which has been highly recommended by the popes. If the hour is made publicly it is designated by a priest or the director; if made privately, any hour is suitable but preferably Thursday or Friday evening. The Passion of Christ is the theme during the hour, variously divided into meditation, vocal prayer, and singing. Many religious communities include the devotion as part of the horarium of their day. (Pocket Catholic Dictionary, by John A. Hardon, S.J.)

What is a monstrance?
A monstrance, a metal vessel usually gold- or silver-plated with a transparent section in which the Sacred Host is placed in its lunette when exposed for adoration or carried in procession. It varies in shape and ornamentation, popular models being tower-shaped or round; a metal circlet surrounded with rays or bars resting on a stem rising from a heavy base, many ornamented with jewels. The monstrance (or ostensorium) in the Cathedral of Toledo took more than a hundred years to make and is reputed to be of gold brought by Columbus from America. (Pocket Catholic Dictionary, by John A. Hardon, S.J.)

Why is exposition in the monstrance preferred?
To see Jesus visibly present under the appearance of the small white host is much more conducive to our intimacy with Him than when He is hidden away in the tabernacle. Moreover, it adds an extra responsibility on the adorers to be sure to be faithful to the hours they are scheduled, since the suggested norm for having Jesus exposed in the monstrance is that there should be at least two adorers present, and He must never be left alone. 
 

What is Benediction?
A Eucharistic devotion in the Catholic Church of the Latin Rite. In its traditional form, a priest, vested in surplice, stole, and cope, places on the altar or in the niche above it the consecrated Host in the ostensorium, or monstrance, and then incenses it.

O Salutaris Hostia or a similar hymn is usually sung at the beginning of exposition, followed by a period of meditation, praise, and adoration by priest and people.

At the conclusion of the ceremony the Tantum Ergo hymn is chanted, with another incensation, and followed by blessing the people with the raised monstrance in the form of a cross.

During the blessing the priest wears the humeral veil covering his hands. Bells are rung during the blessing.

The Divine Praises are then sung or recited by priest and people, and the Blessed Sacrament is reposed in the tabernacle.

Benediction is commonly held on major feasts and Sundays, also during Lent, during a mission, or retreat or during forty hours' devotions. Other days may be designated by individual bishops.

Since the Second Vatican Council the Holy See has simplified the traditional ritual, allowing for a variety of options in the prayers, songs, and readings "to direct the attention of the faithful to the worship of Christ the Lord" (Eucharistiae Sacramentum, 1973, No. 95).

What are some good reasons for establishing Exposition and Adoration?
Some reasons are to provide an easy, attractive, and practical way of rendering God the worship and adoration which is His due as our Creator, of giving Him thanks for our redemption, of making reparation for our sins and the sins of mankind; and of petitioning the good God for the constant help we need.

We also show our gratitude to our Lord for remaining among us in our tabernacles, and to make at least some atonement for the many sacrileges, indifferences, and ingratitude which He receives in His Sacrament of Love.
