This story broke earlier today at the blog of Catholic publisher Ignatius Press. It has reportedly been confirmed by Dr. Noll himself. Then later today Christianity Today published a story online by Rob Moll (no relation, :) ) that details the move.
Interesting, but perhaps not coincidentally, Noll’s move to Notre Dame occurs only months after his book, Is the Reformation Over? was published by Baker Academic on July 1, 2005! For an excellent analysis of this book, click here for a review by Tim Challies.
