The Celtic Christians beheld the world around them and perceived the divine life of God upholding every aspect of the material universe. Their prayers and poems, their liturgies and their theological texts give Christians a sense of faith that is confident in a merciful and infinitely creative, healing God. In this introduction to Celtic Christian spirituality, Mary C. Earle presents the primary texts from the Celtic Christian tradition - selections from the writings of Pelagius, Eriugena and St Patrick, as well as prayers and poems from Wales, the Outer Hebrides and Ireland. These essential texts direct humanity to read the 'book of creation' as well as the book of scripture, and call us to remember that 'matter matters'. The author's engaging facing-page commentary explores how faithful Christians and spiritual seekers use the writings of this lively tradition as ways of embodying and living the gospel.
