"Without prolonged moments of adoration, of prayerful encounter with the word, of sincere conversation with the Lord, our work easily becomes meaningless; we lose energy as a result of weariness and difficulties, and our fervor dies out. The Church urgently needs the deep breath of prayer, and to my great joy groups devoted to prayer and intercession, the prayerful reading of God's word and the perpetual adoration of the Eucharist are growing at every level of ecclesial life."

This practice of adoration is based on strong and solid reasons. For the Eucharist is at once a sacrifice and a sacrament; but it differs from the other sacraments in that it not only produces grace, but contains in a permanent manner the Author of Grace Himself. When, therefore, the Church bids us to adore Christ hidden behind the Eucharistic veils and to pray to Him for spiritual and temporal favors, of which we ever stand in need, she manifests faith in her divine Spouse who is present beneath these veils, she professes her gratitude to Him, and she enjoys the intimacy of His friendship
