What happens when the earliest Christian missionaries to China encounter advanced Tang science, Daoism, and the power of qi? This groundbreaking book takes you inside the lost world of Jingjiao--the Luminous Teaching/Religion--uncovering how these East Syriac missionaries expressed the Holy Spirit through Chinese metaphors of breath and wind. With a fresh English translation of the full Tang Jingjiao corpus--some never before translated with such nuance--you explore a rich constructive theology of creation shaped by interreligious dialogue and scientific insight. Blending theology, Daoism, and Quantum Field Theory, the book introduces Embodied Critical Realism as a bold new method for theology-science-religion trialogue. Read it--and rethink Chinese theology for the third millennium.
