Based on a Christological approach to the relationship between divine love and human, this article advocates for a Christian understanding of the non-duality between self and other - an idea advocated by Mahayana Buddhism in China. The argument consists of three major parts. Firstly, it establishes its doctrinal foundation by retrieving the Christological tradition of the councils of Chalcedon and the Third Constantinople as well as the theology of Maximus the Confessor. Secondly, it demonstrates the Chinese characters of this Christological understanding by engaging into a dialogue with Confucianism on the human love in Jesus Christ and the reciprocity between self and other, and by interpreting the incarnation and exaltation of Jesus Christ from the Buddhist perspective of non-duality of self and other. Thirdly, it further explains its contemporary relevance by illustrating its compatibility with the contemporary inter-disciplinary studies of altruism, and by elaborating its implications for understanding of the relationship between church and society in contemporary China.
