Pope John Paul II
Ecclesia de Eucharistia
The worship of the Eucharist outside of the Mass is of inestimable value for the life of the Church. This worship is strictly linked to the celebration of the Eucharistic Sacrifice. The presence of Christ under the sacred species reserved after Mass -- a presence which lasts as long as the species of bread and of wine remain -- derives from the celebration of the sacrifice and is directed towards communion, both sacramental and spiritual.
It is pleasant to spend time with him, to lie close to his breast like the Beloved Disciple (cf. Jn 13:25) and to feel the infinite love present in his heart. If in our time Christians must be distinguished above all by the 'art of prayer,' how can we not feel a renewed need to spend time in spiritual converse, in silent adoration, in heartfelt love before Christ present in the Most Holy Sacrament? How often, dear brother and sisters, have I experienced this, and drawn from it strength, consolation and support!
This practice, repeatedly praised and recommended by the Magisterium, is supported by the example of many saints. Particularly outstanding in this regard was Saint Alphonsus Liguori, who wrote:Of all devotions, that of adoring Jesus in the Blessed Sacrament is the greatest after the sacraments, the one dearest to God and the one most helpful to us.The Eucharist is a priceless treasure: by not only celebrating it but also by praying before it outside of Mass we are enabled to make contact with the very wellspring of grace.
In the course of the day the faithful should not omit visiting the Blessed Sacrament, which in accordance with liturgical law must be reserved in churches with great reverence in a prominent place. Such visits are a sign of gratitude, an expression of love and an acknowledgment of the Lord's presence.
“Our adoration is a public manifestation of our faith and love, and of our gratitude for this unspeakably great gift. We adore not only the glorified Lord in the Eucharist, but through him, in the Holy Spirit, we also adore the Father. We unite ourselves with his loving surrender to the Father for the life of the world.”
