As the first missionary sinologist comprehensively translated and studied Chinese classics, James Legge provides a meaningful and unique approach to understand Chinese classics, which also inspires Confucian-Christian dialogues. From the monotheist background, James Legge treats the Chinese "Gui Shen" (ghosts or gods) as spiritual beings without divine nature but are subjected to the Absolute One God. In this light, there exists such spiritual beings, and together with "Tian" (Heaven) or "Shang Di" (God). Although invisible and not present, they are watching over each human being all the time. This constitutes an imbalanced relationship of watching and being watched with the Self of human beings. The supervision from these Spiritual Beings reminds the human beings of their absolute responsibilities and obligations. These responsibilities and obligations are embodied in the sacrificial ceremony to the Spiritual Beings, which is to break the "economy of exchanges", cleansing and purifying the sacrificial ceremony into a mere "response" and "devotion" to the Absolute Invisible. Therefore, one of the connections between Confucianism and Christianity is that human beings should respond to the call of the Absolute Invisible and bear their responsibilities without any condition.
