Grounded in the witness of Scripture and informed by the work of such luminaries as Henri de Lubac, Hans Urs von Balthasar, and Pope Benedict XVI (Joseph Ratzinger), this book advances new insight and practical application of the recent retrieval of Trinitarian theology and its vision of human transformation known as deification. Authors Philip Krill and James McCullough aim to articulate for a lay readership a synthesis of the Western and Eastern trajectories of the Catholic Faith and enable them to understand themselves caught up into the full implications of the divinity of Christ and their divinization in him. This second edition includes an expanded glossary that assists in the practical application of theological terminology central to Christian experience.
