Peter Berger makes some interesting parallels between supercessionism for Israel and the Church on the one hand, and Catholics and Protestants on the other.
At one level, his point stands – there are profound discontinuities between that can be lost in anti-supercessionist thinking. On the other hand, I don’t think he quite gets how theological anti-supercessionism actually embraces those differences in ways that supercessionists actually don’t. Once again, not an either/or but a both/and. Many theological supercessionists actually discount the discontinuities he describes (Israel is the OT church; the church is the new Israel, absorbing or inheriting all the OT promises in some form), while some anti-supercessiionists (dispensationalists, in particular) actually emphasize the discontinuities (so much so that Israel maintains a real, separate existence in at least some important respects). So the parallel breaks down, I think.
