Moreover, the wondrous mystery of the Lord’s real presence under the eucharistic species, reaffirmed by the Second Vatican Council and other documents of the Church’s Magisterium in the same sense and with the same words that the Council of Trent had proposed as a matter of faith, is proclaimed in the celebration of Mass not only by means of the very words of consecration, by which Christ becomes present through transubstantiation, but also by that interior disposition and outward expression of supreme reverence and adoration in which the Eucharistic Liturgy is carried out.
– Preamble to the General Instruction of the Roman Missal, 3; emphasis is mine
I’ve started re-reading the whole GIRM from start to finish, and came across this sentence right at the beginning. It strikes me that at times we priests fail to convey to, and foster in, the members of our congregation that “supreme reverence and adoration” that should reflect our faith in the Eucharist. It’s certainly food for thought.
