This is the fourth annual volume of the remarkably popular journal of biblical theology edited by Scott Hahn and his St. Paul Center for Biblical Theology. This volume features important new works by Hahn, Gary Anderson, John Cavadini, Brant Pitre, among others. Inspired by the ground-breaking work of Yves Congar and Jean Danielou, this volume includes original and thought-provoking contributions on such topics as: the Tabernacle and the origins of Christian mysticism; Jesus self-consciousness of being the new Temple and the new High Priest; and the doctrine of the indwelling of the Trinity in the soul; Hahn contributes a new perspective on the Gospel of John, showing how Israel's Temple and feasts are fulfilled in Christ and the sacraments of the Church. As the editors write in their introduction to this volume: The Temple theme is perhaps the richest in all of biblical theology, embracing the mysteries of Christ, Church, and Kingdom; liturgy, sacraments, and priesthood; salvation, sanctification, and divine filiation. These are the beautiful mysteries we contemplate in this volume of Letter & Spirit.
