A Systematic Theology from East Asia: Jung Young Lee's Biblical-Cultural Trinity considers the Trinitarian theology of Jung Young Lee, a twentieth-century Korean American theologian, unique for being based on the Bible but also inspired by the Book of Changes, a classical text from East Asian culture with wide appeal. This monograph examines the Christian scriptural-traditional and cultural roots of Lee's doctrines of God and the Trinity as twin pillars of his systematic theological system bearing out God's nature, purposes, and guidance for humanity and the world. In addition, this book outlines the autobiographical milieu of Lee's theology, its contribution to three distinct fields of Trinitarian doctrine (immanent-economic trinitarianism, social Trinity theory, and Cappadocian trinitarianism), and culminates in an assessment of Lee as a systematic theologian from East Asia, comparing Lee with other Asian American theologians.
