Pope Benedict XVI visits the UK between 16 and 19 September 2010. We know that he leads the Catholic Church, we know there is controversy over the way he responded to the abuse of children by clergy, we may have read his controversial statements on Islam. But what is the theology that underlies the Pope's thinking? Covenant and Communion reveals the hidden key that unlocks the mind of Benedict XVI. The first half of the twentieth century saw the emergence of three renewal movements in Catholic thought - the biblical, the patristic and the liturgical.These movements converge and flourish in Benedict's theology as never before. Scott Hahn is one of the best-selling contemporary Catholic writers. His introduction to what he describes as 'a theology of great power and beauty' is vivid and enthralling.
