As Protestants, we believe the following:
1. The incarnation of Christ was “once for all”
2. Christ’s death and resurrection and our redemption were “once for all”
3. “Revelation” was “once for all delivered to the saints”.
Roman Catholicism flips these precisely on their head:
1. The Roman Catholic Church is the “ongoing incarnation of Christ” (“for evermore”)
2. “The Eucharist” (“the sacrifice of the Mass”) is a “re-presentation” of the one sacrifice of Christ, providing redemption on an ongoing basis (“for evermore”) throughout time.
3. The “once for all” sense of biblical revelation is opened up to being integrated with “living Tradition” that is mediated by the Magisterium, creating a dialectic between the biblical message and the process of tradition.
De Chirico’s original Themelios (2004) article is here.
In it, he suggests “Roman Catholicism is not intentionally driven by the desire to confuse the time periods of God. It would be uncharitable and prejudiced to think so,” he says.
However, Roman Catholicism IS driven to exalt itself: “Rome IS all about aggrandizing Rome”. And if it means distorting the Biblical message about God’s work in time, it has no hesitation to do so. This is not at all “uncharitable and prejudiced to think so”, because it is true.
