That God is the perfection of all-blessed wholeness, and the source and context for creation's well-being, tends merely to be assumed in theology. Yet, how does God actualize God's own abundantly enriched life? And how might such a reality be relevant to human well-being? Addressing these questions, this book traces the dynamics of Divine well-being through Scripture, Christian metaphysics, and a synthesis of Orthodox (Bulgakov), Catholic (Von Balthasar), and Protestant (Pannenberg) Trinitarian theologies to argue that God's 'all-blessed' life, the glory of well-being, is symbiotic with triune self-giving (kenosis); a concept identified as 'kenotic-enrichment' or 'enriching-kenosis.' Such a trinitarian exploration not only offers a fresh perspective on the contested topic of kenosis but goes to the heart of a doctrine of God that implicates the possibility of human well-being. Triune Well-Being makes a genuine and original contribution to systematic scholarship on the doctrine of the Trinity whilst never losing sight of the practical implications for humanity. Ultimately, Jacqueline Service invites the reader into the transformative beauty of worship, where the very pattern of God's well-being is, not surprisingly, the ontological origin and deep patterning for the well-being of all life.
