Decalogue: A term used by Clement of Alexandria…”And the Decalogue, viewed as an image of heaven, embraces sun and moon, stars, clouds, light, wind, water, air, darkness, fire. This is the physical Decalogue of the heaven. And the representation of the earth contains men, cattle, reptiles, wild beasts; and of the inhabitants of the water, fishes and whales; and again, of the winged tribes, those that are carnivorous, and those that rise mild food; and of plants likewise, both fruit-bearing and barren. This is the physical Decalogue of the earth. And there is a ten in man himself: the five senses, and the power of
speech, and that of reproduction; and the eighth is the spiritual principle communicated at his creation; and the ninth the ruling faculty of the soul; and tenth, there is the distinctive characteristic of the Holy Spirit, which comes to him through faith. “

Demiurge: Meaning ‘Creator’ in Greek. Thought to be the “Craftsman” or creator of the material world. (Heracleon) In Orthodox thought this is a supernatural entity or force, such as the appearance of God to Moses. In the Gnostic schema the Word refers to an order, and it may be a natural sort of intelligent design, related to wisdom, the earthly or kenomic state of the higher wisdom, or form from the Pleroma. The material state is considered less than the Pleromic, and highly flawed. Archons seem to be emanations from the Demiurge process, much like other emanations from the Pleroma. (See; Pleroma, Kenoma, Archon.)
