'No true Christian could vote for Donald Trump.' 'Real Christians are pro-life.' 'You can't be a Christian and support gay marriage.' Assertive statements like these not only reflect growing religious polarization but also express the anxiety over religious identity that pervades modern American Christianity. To address this disquiet, conservative Christians have sought security and stability: whether by retrieving 'historic Christian' doctrines, reconceptualizing their faith as a distinct culture, or reinforcing a political vision of what it means to be a follower of God in a corrupt world. The result is a concerted effort 'Make Christianity Great Again': a religious project predating the corresponding political effort to 'Make America Great Again.' Part intellectual history, part nuanced argument for change, this timely book explores why the question of what defines Christianity has become, over the last century, so damagingly vexatious - and how believers might conceive of it differently in future.

Far from being solely an academic enterprise, the practice of theology can pique the interest of anyone who wonders about the meaning of life. This introduction to Christian theology – exploring its basic concepts, confessional content, and history – emphasizes the relevance of the key convictions of Christian faith to the challenges of today's world. Part I introduces the project of Christian theology and sketches the critical context that confronts Christian thought and practice today. Part II offers a survey of the key doctrinal themes of Christian theology, including revelation, the triune God, and the world as creation, identifying their biblical basis and the highlights of their historical development before giving a systematic evaluation of each theme. Part III provides an overview of Christian theology from the early church to the present. Thoroughly revised and updated, the second edition of An Introduction to Christian Theology includes a range of new visual and pedagogical features, including images, diagrams, tables, and more than eighty text boxes, which call attention to special emphases, observations, and applications to help deepen student engagement.
