The Confucian Theological System
Based on context alone The Confucian theological system was a rather complicated concept. In traditional Confucian thought, it was not a typical and complete theological system like religion. However, in the course of its development, it gradually integrated some elements with theological colors. In the Confucian school of thought, the 'Heaven' had a supreme status and was viewed as a dominating existence. " Heaven " could control the fate of all things in the world, the rise and fall of dynasties, and so on. For example, ancient emperors were often called " Son of Heaven ", indicating that their power was ordered by Heaven. At the same time, the concept of " destiny " was also a part of Confucianism that was closely related to mythology. People's behavior and morality were believed to be related to destiny. A gentleman had to act according to destiny. This contained a concept that surpassed the power of human beings. In terms of sacrificial offerings, the scholarly faction placed great importance on offering sacrifices to their ancestors, the heavens, the earth, and the mountains. Sacrifice to ancestors was seen as a manifestation of filial piety and respect for family inheritance, while sacrifice to heaven, earth, mountains, rivers, and so on reflected respect for natural and supernatural forces. There were strict rules of etiquette in the process of sacrifice, and behind these rules of etiquette, it also reflected the respect for supernatural forces. In a sense, it had a theological hint. In addition, in the later stages of the development of Confucianism, phenomena such as divination appeared. Divination mixed a large number of auspicious signs and disasters, connecting natural phenomena with the good or bad luck of human affairs, and explained Confucian classics in a mysterious way. This situation was more popular in the Han Dynasty and other periods. However, from the mainstream and essence of Confucianism, these theological parts were more of an auxiliary element to help maintain the feudal rule order and regulate social morality. The core was still concerned with the moral relationship in the real world.
