Peter Leithart has a book coming out called The End of Protestantism. The title is intentionally provocative. Peter has long held the position that reformation is something the church should always be doing; protesting, on the other hand, is not.
By that he means that the church should not work toward a greater and greater fracturing of denominations; rather, we should work toward a reformation that once more unifies the church catholic. It has been my contention, borrowing from Leithart and others, that rather than protesting the church, we should should work toward healing a church that has long been separated. Mind you, this does not entail swimming the Tiber to Rome. But it does entail working with those in Rome and Constantinople et al. It means taking seriously those differences that divide and working toward overcoming them. We should not take lightly the positions of Rome and Eastern Orthodoxy. In fact, we should engage them. When we brush the issues aside, we create larger rifts in the church. This undoubtedly grieves Christ, who prayed for the unity of his church (which, by the way, is his one mystical body!) before his death (John 17).
To say the least, I’m really looking forward to this book! Here’s a little preview below on his stance toward denominations, one that I also hold.
