David Oberson illuminates Thomas Merton’s unique view of his own society, aiding Christians in navigating a post-Christian, post-truth world. Thomas Merton proclaimed, over sixty years ago, that we were living in a post-Christian world. Since then, in an increasingly secular society where the influence of the institutional church is under doubt, Thomas Merton's reflections are more salient than ever. David Oberon's discussion and analysis brings this mystic, monk and spiritual leader's view of the opportunities presented to Christians by cultural changes to the forefront, focussing on how the individual's witness can take precedence. Oberon situates the reader in the current cultural context, and handles Merton's work with care and clarity. He illuminates Thomas Merton's unique view of his own society, which credibly speaks to our present, aiding Christians in navigating a post-Christian, post-truth world.
