AbstractThe concept of love occupies a central position not only in the Lutheran–Augustinian theology of justification and sanctification, but also in some traditional Chinese religions such as Confucianism, Buddhism and Taoism. For the Finnish interpretation of Luther's theology, a range of pivotal concepts such as two kinds of love, union (participation), gift, favor, unifying power, as well as the real‐ontic presence in faith act a fundamental role in addressing the doctrine of justification and divinization. As a new research approach, the formulation of unio cum Christo in Spiritu sancto develops Tuomo Mannermaa's interpretation of in ipsa fide Christus adest thus opening a new dialogue with the relational creativity of love in Chinese Tao‐Qi framework. While the ontological presuppositions of these two religious traditions are different, the relational love can be explored as a new conceptual model for deepening the theoretical communications between Lutheran theology and Chinese faith traditions.
