As the first priest of Protestantism in China, Liang Fa played an important and special role in the history of Christianity in China. He studied the Four Books and the Five Classics when he was young and became a Buddhist afterwards, which made his theological ideas complex and characteristic. For the sake of making Christianity understandable to the Chinese, Liang rebuilt and made use of the ideas of the Chinese traditional culture to interpret the Christian Theology. His interpretation conformed to the three points of Sino-Christian theology suggested by Prof. He Guanghu, which are "inside out," "from a plane to a point" and "buttom-up". In this article, we discuss the theological ideas and approach of Liang Fa. And we hope that the experience of Liang Fa can be a reference for the construction of Sino-Christian Theology.
