Eucharistic Adoration: “is an extension of the adoration of the Blessed Sacrament which occurs in every Mass: "Behold the Lamb of God, behold him who takes away the sins of the world. Blessed are those called to the supper of the Lamb." Exposition of the Blessed Sacrament flows from the sacrifice of the Mass and serves to deepen our hunger for Communion with Christ and the rest of the Church.
A Holy Hour is the Roman Catholic devotional tradition of spending an hour in Eucharistic Adoration in the presence of the Blessed Sacrament. It is a powerful and beautiful way to grow closer to Jesus.
To put it simply, we make a Holy Hour to be present with God, When Christ was in agony in Gethsemane, he turned to prayer (Mt.26:40). In our own agony, suffering or even gratitude, we can also turn to prayer as Christ did.
"The Church and the world have a great need for Eucharistic worship. Jesus awaits us in this sacrament of love. Let us not refuse the time to go to meet him in adoration, in contemplation full of faith, and open to making amends for the serious offenses and crimes of the world. Let our adoration never cease."
