'Quite simply, a remarkable piece of writing and scholarship, quite the best book by a British theologian I have read this year ... a brilliant achievement ... Davies writes with passion and verve ... I hope it is read widely, and studied carefully ... warmly recommended.' Reviews in Religion and Theology ' ... a welcome introduction to a difficult but rewarding subject ... a stimulating and attractive book, which will do much to encourage study a early Welsh Christianity.' Journal of Ecclesiastical History ' ... the best and most thorough exploration of the spirituality of early medieval Wales to date ... the real treasure, finally managing to put some theological depth into the histroical and literary surveys of Welsh Christianity in its earliest centuries.' Planet 'Epoch making...A book which alters our whole picture of the Welsh element in Celtic Christianity...written with an enthusiasm which communicates itself to the reader.' Church Times
