Book excerpt: This is the introductory volume of a multivolume, verse-by-verse, interfaith rereading of the New Testament letter to the Ephesians. It looks to the Tiantai Buddhist master Zhiyi and his "threefold truth" to enhance our appreciation of nascent trinitarian themes in Ephesians. And it draws upon a broad array of scientific, theological, and philosophical thinkers in aid of rejecting the epistle's ancient, geocentric cosmology and its accommodations to the misogynistic, patriarchal, and slaveholding norms of its first-century surroundings. As a whole, the work constitutes a twenty-first century apologetic for doctrinal humility and for theologizing within a global theological commons.
