Huh? What are you talking about? How can 24/7 Adoration not virtually shout "The Real Presence?"
"How can 24/7 Adoration not virtually shout 'The Real Presence?'"
You really don't get it. Most of the world's Catholics will never attend one of these devotions. Most have only the slightest acquaintance with the dogma of the Real Presence due to its suppression in the Novus Ordo Liturgy. Polls bear this out.
Ask yourself--when was the last time you knelt for Communion? When did you last receive Communion on the tongue? Why has the tabernacle been removed from its central place of honor in the sanctuary? Why were the words "Mystery of faith" transposed from the liturgical text in such a way as to NOT refer to the reality of Transubstantiation? Many more such questions come to mind--but these suffice to prove my point.
In fact, Cardinal Ratzinger himself has pointed to the danger that liturgists and bishops pose by interpreting the Novus Ordo in opposition to Trent:
"It is only against this background of the effective denial of the authority of Trent, that the bitterness of the struggle against allowing the celebration of Mass according to the 1962 Missal, after the liturgical reform, can be understood. The possibility of so celebrating constitutes the strongest, and thus (for them) the most intolerable contradiction of the opinion of those who believe that the faith in the Eucharist formulated by Trent has lost its value."
