Encyclical Letter on the Holy Eucharist - Parts 24 & 25

24. The gift of Christ and his Spirit which we receive in Eucharistic communion superabundantly fulfils the yearning for fraternal unity deeply rooted in the human heart; at the same time it elevates the experience of fraternity already present in our common sharing at the same Eucharistic table to a degree which far surpasses that of the simple human experience of sharing a meal. Through her communion with the body of Christ the Church comes to be ever more profoundly “in Christ in the nature of a sacrament, that is, a sign and instrument of intimate unity with God and of the unity of the whole human race”.⁴⁴

The seeds of disunity, which daily experience shows to be so deeply rooted in humanity as a result of sin, are countered by the unifying power of the body of Christ. The Eucharist, precisely by building up the Church, creates human community. 

25. 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 ⁴⁵ – derives from the celebration of the sacrifice and is directed towards communion, both sacramental and spiritual.⁴⁶ It is the responsibility of Pastors to encourage, also by their personal witness, the practice of Eucharistic adoration, and exposition of the Blessed Sacrament in particular, as well as prayer of adoration before Christ present under the Eucharistic species.⁴⁷

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”,⁴⁸ 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,⁴⁹ 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”.⁵⁰ 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. A Christian community desirous of contemplating the face of Christ in the spirit which I proposed in the Apostolic Letters Novo Millennio Ineunte and Rosarium Virginis Mariae cannot fail also to develop this aspect of Eucharistic worship, which prolongs and increases the fruits of our communion in the body and blood of the Lord.
