"In the Eucharist, the Son of God comes to meet us and desires to become one with us; Eucharistic adoration is simply the natural consequence of the Eucharistic celebration, which is itself the Church’s supreme act of adoration. Receiving the Eucharist means adoring Him whom we receive. Only in this way do we become one with Him, and are given, as it were, a foretaste of the beauty of the heavenly liturgy. The act of adoration outside Mass prolongs and intensifies all that takes place during the liturgical celebration itself."
Pope Emeritus Benedict XVI
