Contrary to David R. Law, Mathias Hassenfratz-Coffinet considers that Thomasius’ approach is more promising than Weston’s. The latter’s dualistic anthropology (body/soul), the question of the meaning of incarnation for God and the risk of docetism are problematic, and metaphysics seems to overrule theology in his system. With Thomasius, a perfectly « self-determined » vision of God is problematic, yet the humanity of Christ as well as Jesus’ human development are treated in the better way.
