In his column-- a critique of the new, more accurate liturgical translations that reflect the content and dignity of the original Latin-- Father Kelly writes:
Regrettably, all too frequently, the only Presence focused on is Christ’s presence in the elements of bread and wine. Inadequately described as the change of the “substance” (not the “accidents”) of bread and wine into the body and blood of Christ, the mystery of the real presence of Christ in the Eucharist carries the intellectual baggage of a physics no one accepts. Aristotelian physics makes such nice, however implausible and now unintelligible, distinctions. They are meaningless in the post-Newtonian world of quantum physics, which is the scientific context we live in today.
The Catechism of the Catholic Church, on the other hand, teaches:
The Council of Trent summarizes the Catholic faith by declaring: "Because Christ our Redeemer said that it was truly his body that he was offering under the species of bread, it has always been the conviction of the Church of God, and this holy Council now declares again, that by the consecration of the bread and wine there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord and of the whole substance of the wine into the substance of his blood. This change the holy Catholic Church has fittingly and properly called transubstantiation." (no. 1376)SIC: CC
