My latest book, co-autored with Mike Reeves, is Why the Reformation Still Matters. It’s published in the UK by IVP on 21 April 2016 and in the US by Crossway in September 2016. Next year is the 500th anniversary of the nailing of the 95 theses by Martin Luther to the door of the Castle Church in Wittenberg. This event will receive plenty of coverage in the media, but the tone is likely to imply either that the Reformation was an unfortunate squabble over irrelevant issues or that the Reformation is over. So Mike and I wanted to write a book that shows why it still matters. It matters for our interaction with Catholicism, but we also argue that in many ways evangelicals also need to rediscover the truths of the Reformation.
