- the Cosmos of time and matter, in which we live;
- The spiritual realm of the angels and spiritual beings (including the resurrected human person);
- The One, or God.
- There is the relative eternity of spiritual beings not in the matter/time cosmos;
- There is the absolute eternity of God and in God. Absolute eternity is independent of creation, whether spiritual (invisible) or material (visible)
- Are the Son and Spirit simply a part of the Cosmos? This would lead to the heresies of adoptionaism or modalism;
- Are the part of the non-temporal spiritual realm which is distinct from the One but prior to the Cosmos? Are they spirit beings (Angels)? This is a form of eminationism, similar to wht we see in Gnosticism or neoplatonism. If so, can we worship them?
- Are they in the eternal one? If so, how can we maintain that there is one God?
Certain texts, especially in St Maximos the Confessor, also use the word aeon in a connected but much more specific way, to denote a level intermediate between eternity in the full sense (...aidiotes) and time as known to us in our present experience (...chronos)....There are thus three levels:(a) eternity, the totum simul or simultaneous presence of all time and reality as known to God, who alone has neither origin nor end, and who is therefore alone eternal in the full sense;(b) The aeon, or totum simul as known to the angels, and also to human persons who possess experience of the 'age to come': although having no end, these angelic or human beings, because they are created, are not self-originating, and therefore are not eternal in the sense that God is eternal;(c) time, that is temporal succession as known to us in the 'present age'.
