Might this apply to Confucianism, is that what you mean, or perhaps to some of its adherents - or is your observation more aimed at my suggestion that for religions to be religions they have to have deities and/or supernatural elements?
What remains consistent throughout Confucius' discourses on Tian is his threefold assumption about this extrahuman, absolute power in the universe: (1) its alignment with moral goodness, (2) its dependence on human agents to actualize its will, and (3) the variable, unpredictable nature of its associations with mortal actors. Thus, to the extent that the Confucius of the Analects is concerned with justifying the ways of Tian to humanity, he tends to do so without questioning these three assumptions about the nature of Tian, which are rooted deeply in the Chinese past.
The dependence of Tian upon human agents to put its will into practice helps account for Confucius' insistence on moral, political, social, and even religious activism. In one passage (17.19), Confucius seems to believe that, just as Tian does not speak but yet accomplishes its will for the cosmos, so too can he remain "silent" (in the sense of being out of office, perhaps) and yet effective in promoting his principles, possibly through the many disciples he trained for government service. At any rate, much of Confucius' teaching is directed toward the maintenance of three interlocking kinds of order: (1) aesthetic, (2) moral, and (3) social. The instrument for effecting and emulating all three is li (ritual propriety).
Do not look at, do not listen to, do not speak of, do not do whatever is contrary to ritual propriety. (12.1)
In this passage, Confucius underscores the crucial importance of rigorous attention to li as a kind of self-replicating blueprint for good manners and taste, morality, and social order. In his view, the appropriate use of a quotation from the Classic of Poetry (Shijing), the perfect execution of guest-host etiquette, and the correct performance of court ritual all serve a common end: they regulate and maintain order. The nature of this order is, as mentioned above, threefold. It is aesthetic -- quoting the Shijing upholds the cultural hegemony of Zhou literature and the conventions of elite good taste. Moreover, it is moral -- good manners demonstrate both concern for others and a sense of one's place. Finally, it is social -- rituals properly performed duplicate ideal hierarchies of power, whether between ruler and subject, parent and child, or husband and wife. For Confucius, the paramount example of harmonious social order seems to be xiao (filial piety), of which jing (reverence) is the key quality:
Observe what a person has in mind to do when his father is alive, and then observe what he does when his father is dead. If, for three years, he makes no changes to his father's ways, he can be said to be a good son. (1.11)
[The disciple] Ziyu asked about filial piety. The Master said, "Nowadays, for a person to be filial means no more than that he is able to provide his parents with food. Even dogs and horses are provided with food. If a person shows no reverence, where is the difference?" (2.7)
In serving your father and mother, you ought to dissuade them from doing wrong in the gentlest way. If you see your advice being ignored, you should not become disobedient but should remain reverent. You should not complain even if you are distressed. (4.18)
Above quoted from:
Sounds like a religion to me. The element of reverence is present, which it is not in, for example, Stoicism. Stoicism is therefore a philosophy, not a religion, in my view.
