The study of Christian theology in the last half century has seen a major renaissance in Trinitarian thought which has attempted to connect Trinitarian theology to all aspects of Christian faith and practice. This revival has often addressed the unfortunate split which has haunted much modern theological endeavour between theology and both prayer and practice, the disjunction between thought about God and the movement of the heart toward God in transformed lives. With contributions from Oliver O' Donovan, Rowan Williams, Andrew Louth and Ayla Lepine 'A Transforming Vision' explores what it means to know and love the Triune God, and how the knowledge of God can be a transforming and saving knowledge.
