"I didn't say this, I didn't say that"
You claim these souls will have Original Sin remitted at/after the Second Coming. Original Sin being the impediment to a soul enjoying the Beatific Vision.
You claim this will be a "similar event" to Our Lord's Sacrifice, which He offered ONCE, on the cross, for the redemption of mankind. Mankind. Was redeemed. ONCE. This same Redemption is what enabled the OT Just to attain the Beatific Vision.
So you are either saying some will have Original Sin remitted and will not be able to enjoy the BV, or you are saying the BV is not enjoyed for eternity
