If all shall be saved, parousia can never happen because "all" is infinite pool
Help me work through this.
This occurred to me in my other post where the topic of identity depending on reality of other people is said to be necessary for meaningful concept of me.
If that is so, we need all past, present, and future souls to be saved in order to have completeness.
But "all future souls" come from infinite pool of existence. There is never an end to them, and if God makes a cut-off and all up to that point are saved, we run into the same problem frequently mentioned here, that is, someone dying is an arbitrary cutoff point for them to be saved. In the same fashion, someone not being born/conceived is an arbitrary cutoff point for them, pre-existence of souls must be implied here. So the end can never happen, otherwise those unrealized souls never got the chance to be saved.
If God can decide to bring about the judgment and salvation of all at some point, thereby cutting off those not conceived from existing, he can do the same with those who were born. In any case, someone is left out.
The alternative is that there is a pre-fixed number of souls and we are waiting for them to be realized, but that doesn't sound right to me metaphysically.
