Prof. Yu’s main concern is to relate the Christian faith to the contemporary cultural context, in particular to the Chinese context under the impact of globalization. How is the Christian faith relevant to the preservation of the Chinese humanist tradition when market capitalism is uprooting traditional spiritual values? How is the Christian critique of Western liberalism relevant to the search for a new form of liberty that brings together freedom and commitment? How is the Christian critique of market capitalism relevant to present trends in economic development in China?
Prof. Yu has taught courses like Dogmatic Theology, The Gospel and Hong Kong Society, The Christian Faith and Contemporary Thought, The Christian Faith and Chinese Culture, Christian Faith and Modern Literature.
