Traces of the Trinity appear in myriad ways in everyday life, from our relations with the world and our relationships with others to sexuality, time, language, music, ethics, and logic. In this evocative book, Peter Leithart explores the pattern of mutual indwelling that characterises the creation at every level. This small book with a big idea - the Trinity as the Christian theory of everything - changes the way we view and think about the world and places demands on the way we live together in community.
