Listening for the Heartbeat of God: A Celtic Spirituality

Here's the book that most teachers, pastors and pilgrimage leaders will hand you straight away to learn about the voice of J. Philip Newell, who ranks pretty much as the American standard-bearer of the global Iona Community -- and the most popular advocate, in America, for a theology that he describes as Celtic.
We're listing it second here under Philip's name, because many readers may simply want to dive into the prayers and daily meditations themselves. This book contains prayers, but is more of a historical introduction to this movement than a guidebook to personal reflections.
In keeping with this plain-speaking revival of ancient religious forms, Newell's book is just a wee bit over 100 pages and yet it gives us a wonderfully breezy tour through centuries of reflection in this school of spirituality.
If you're even considering a trip to Iona, this is a "must buy" book, partly to understand how the current leaders of the Iona movement understand their history.
