Beginning or Origin
Arche is an interesting word. We find a lot of other words that come from it such as Archangel, which is a principle or chief angel, an original angel, an angel that is emanating that Arch. In other words, an Archangel is superior to that of a regular Angel because it has fully or more developed that Arche, that original activity, it is closer to that origin.
There is also a word used a lot called Archetype. Archetype means a primordial mold. An archetype is like a blueprint for something that must be developed within our self. We have these potential connections, like I said prior, our soul is connected to our spirit and our spirit is connected to Christ, and Christ is manifested in many different archetypes, many different ways in which the light is formed.
