Vatican Council, the Catholic church has made Eucharistic exposition and benediction a liturgical service in its own and exercised more direction over its practice; it draws its primary meaning from the Eucharistic celebration itself. "By worshiping the Eucharistic Jesus, we become what God wants us to be! Like a magnet, The Lord draws us to Himself and gently transforms us." At the beginning of the exposition of the Blessed Sacrament, a priest or deacon removes the sacred host from the tabernacle and places it in the monstrance on the altar for adoration by the faithful. A monstrance is the vessel used to display the consecrated Eucharistic Host, during Eucharistic adoration or benediction.

Speaking to a gathering in Phoenix Park, during a three-day visit to Ireland, from 29 September – 1 October 1979, Pope John Paul II said,The visit to the Blessed Sacrament is a great treasure of the Catholic faith. It nourishes social love and gives us opportunities for adoration and thanksgiving, for reparation and supplication. Benediction of the Blessed Sacrament, Exposition and Adoration of the Blessed Sacrament, Holy Hours, and Eucharistic processions are likewise precious element of your heritage--in full accord with the teaching of the Second Vatican Council." As to the manner in which Eucharistic adoration is conducted, the "Instructions" state: "Even brief exposition of the Blessed Sacrament, ...should be so arranged that before the blessing with the Blessed Sacrament reasonable time is provided for readings of the Word of God, hymns, prayers, and silent prayer, as circumstances permit."
