Book excerpt: This book shows that theology is both integrally related to formation in Jesus Christ and shapes our understanding of the world. Christian formation is incomplete and impossible without theological formation, because Christ transforms our hearts and minds, attuning them to the reality of God. As the authors explore the deep connections between theology and the life of the Christian, they emphasize Christian formation as a defining feature of the church, arguing that theology must be integrally connected to the church's traditions and practices.
