Whether or not Confucius was theist, that would have to be a mistranslation. There is no reasonable identity between any of Confucius's references and "the will of God".SAM said:Confucius says: "There are three things of which the supreme man stands in awe. He stands in awe of the will of God, he stands in awe of great sages and of the inspired words which have been uttered by such men"
Much of the standard translations of the writings of the early Chinese philosophers is by Western and Western missionary educated Christians, and they have famously introduced many concepts and viewpoints that don't belong in Chinese thought of the time - often, trivializations; occasionally, serious errors.
If you want to treat the various spirits, ancestors, supernatural beings, and so forth, of Chinese religion as gods in the Western sense, that is your privilege. Confucius himself emphasized the importance of ritual and submission to one's role in society, for maintaining order and establishing virtue. His visible theistic beliefs in this regard, if any, bore very little similarity to the Abrahamic God.
