This book re-imagines the universe (and the scientific study of it) through the lens of a triune Creator, three persons of irreducible identity in a perichoretic or coinherent communion. It modestly proposes that Trinitarian theology, and especially the coinherent natures of the Son in the incarnation, provides the metaphysic or ""theory of everything"" that manifests itself in the subject matter of science. The presence of the image of the triune God in humanity and of traces of this God in the non-human creation are discussed, highlighting ontological resonances between God and creation (resonances between the being of God and his creation), such as goodness, immensity-yet-particularity, intelligibility, agency, relationality, and beauty. This Trinitarian reality suggests there should be a similarity also with respect to how we know in theology and science (critical realism), something reflected in the history of ideas in each. These resonances lead to the conclusion that the disciplines of theology and science are, in fact, coinherent, not conflicted. This involves recognition of both the mutuality of these vocations and also, importantly, their particularity. Science, its own distinct guild, yet finds its place ensconced within an encyclopedic theology, and subject to first-order, credal theology. ""'Trinitarian theology as a ""theory of everything""'!? Unlike Raimon Panikkar or David Bohm, Ross Hastings' vision of triune coinherence between reality and our faithful knowledge of it is deeply rooted in the classical Christian tradition. Here, historic orthodoxy meets late modern science in a mutually indwelling and illuminating encounter."" --Amos Yong, author of The Spirit of Creation: Modern Science and Divine Action in the Pentecostal-Charismatic Imagination ""Many have read Ian Barbour's four modes of relating science and theology: conflict, independence, dialogue, or integration. Theologian Ross Hastings reflects on another mode: coinherence. Drawing on the coinherent nature of the Trinity itself, Hastings brings an explicitly Christ-centered approach to a conversation that too often degenerates to mere deism. Hastings' in-depth theological work, informed by his background in chemistry, is a valuable and welcome resource for understanding science in light of Christian faith.""   --Deborah Haarsma, President of BioLogos ""This is a courageous and thought-provoking discussion of the significance of God's Triune identity for how we think about the nature of the contingent order. Ross Hastings' unique cross-disciplinary abilities as an academic theologian who is also a highly qualified scientist facilitate analysis that is not only informed but profound in the insights it offers."" --Alan J.
