Just a short post exploring a possibility. The ‘eschaton’, with the concept of the ‘end’, the age to come etc., is the common word used to describe what is coming. Hence the events (many past) which will include Easter, Pentecost can be described as eschatological events. We then have in that wonderful chapter of 1 Cor. 15 such statements as ‘The last (eschatos) enemy to be destroyed is death’ and Jesus is describes as the ‘Last (eschatos) Adam’.
The word telos is also a word for end but more in terms of a goal to be attained to, so is there a significance that eschatos is used not telos?
Maybe it indicates that the eschatos is bringing all of creation not through to its ‘goal’ in the sense of final destination but to its place of fullness through which multiple ‘goals’ can be reached. Maturity might not be the finality but the removal of the potential to foul up the self-giving purposes of God, hence the list of ‘no mores’ when the ‘end’ (new beginning?) comes, and the burning up in the lake of fire of all that is oppressive.
Just a random thought.
