Could you please inform us of what you know of this "age to come" that is not part of eternity? Not just AN age but THE age. I am ignorant about it (as with many things)
I am not sure how much I know about the age to come, but as one who believes in a millenium of peace following Christ's return, I have no doubt that the millenium itself constitutes that age.
Unless I misunderstand you, you do not dispute that the statement is an antithesis, you take aionios punishment and aionios life to be both of an indeterminate period, neither one being eternal or forever.
Close, but not quite. I have not been saying "neither one being eternal or forever" in actuality. I have been saying that implicit in the meaning of "aionios" is neither the concept of a period of time that has an end, nor a period of time that goes on forever, but rather the concept of time going on from age to age. Future ages themselves may go on forever.
I don't fully understand this question, but I hope I have answered in my reply to the previous one. You speak of the "end of eternal life." Eternal life, of course has no end. But if you mean "aionios life", that is, "life which goes from age to age", the meaning does not tell us that it is eternal. That which goes from age to age may come to an end or it may not. I believe, with you, that "aionios" life does not come to an end. I believe it "goes from age to age" and that there is no end to future ages.What happens to the saved when they come to the end of eternal life, or is it eternal probation?
I believe, with you, that our Lord's statements about the aionios life of the sheep and the aionos correction of the goats are parallel statements.
Augustine, the first in the church to promote the concept of everlasting punishment, also used the same argument against the majority in the church who did not hold to this belief.
Augustine probably got the idea from the Manicheans with whom he associated in his younger years. The Manicheans held that there is an eternal struggle between good and evil. When he returned to the catholic church with its teaching of the victory of Christ, it would be a small step to think of Christ being the victor by punishing his enemies eternally.
However, to get back to my own position. Those who are lost, whether in this life or in the next, can be found. Christ came to save those who are lost. The "goats" will be corrected in Gehenna, the Lake of Fire, for ages and ages. Their correction will be "aionios", that is, it will go from age to age. Yet it will come to and end when they are reconciled to God.
For in him all the fulness of God was pleased to dwell, and through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross. Colossians 1:19,20
So that which "goes from age to age" may come to an end, that is, not continue throughout the unending ages, as is the case with those who will be corrected in The Lake of Fire, or that which "goes from age to age" may continue going from age to age forever, as in the case of those who are learners and followers of Christ. There is nothing inherent in the meaning of "aionios" which determines which of the two it will be.
