Brenk, Frederick (January 2016). „Pagan Monotheism and Pagan Cult“, “Theism” and Related Categories in the Study of Ancient Religions, SCS/AIA Annual Meeting. Philadelphia: Society for Classical Studies (University of Pennsylvania). „Historical authors generally refer to “the divine” (to theion) or “the supernatural” (to daimonion) rather than simply “God.” [...] The Stoics, believed in a God identifiable with the logos or hegemonikon (reason or leading principle) of the universe and downgraded the traditional gods, who even disappear during the conflagration (ekpyrosis). Yet, the Stoics apparently did not practice a cult to this God. Middle and Later Platonists, who spoke of a supreme God, in philosophical discourse, generally speak of this God, not the gods, as responsible for the creation and providence of the universe. They, too, however, do not seem to have directly practiced a religious cult to their God.“
