The souls of the wicked are not immortal. That is denied to them.

I take it by this answer that you believe the souls of the wicked are annihilated after this life; is that correct? What happens to them?

If you want ANOTHER church father I would suggest A Treatise on the Soul by Tertullian where he states:

whereas the soul is immortal; and being immortal, it is therefore indissoluble; and being indissoluble, it is figureless: for if, on the contrary, it had figure, it would be of a composite and structural formation.

For in this philosophy lie both their Æons and their genealogies. Thus, too, do they divide sensation, both into the intellectual powers from their spiritual seed, and the sensuous faculties from the animal, which cannot by any means comprehend spiritual things.

The truth is, the soul is indivisible, because it is immortal; (and this fact) compels us to believe that death itself is an indivisible process, accruing indivisibly to the soul, not indeed because it is immortal, but because it is indivisible.

If this isn't enough, the Catholic website NewAdvent is very clear:

As we have already observed, the immortality of the human soul is one of the most fundamental tenets of the Christian Religion. -New Advent - Immortality

Sorry, on this one the Catholic Church and Protestant Church both agree, the soul is created at birth and is immortal. If the Orthodox does not believe that then I would suggest they check with their Catholic friends. You are simply trying a back handed attempt at making a case for the annihilation of the wicked. Sorry that won't work.

Tertullian was a heretic and the Latins, as in other matters, are simply wrong. The quoted position is from the Middle Ages after Rome broke from the other Patriarchates. Rome picked up a lot of odd stuff after the Great Schism. Some of those oddities lead to the Reformation. More later; off to an Armenian dance where I can say all the bad things about Turks I want!

Tertullian is not a Church Father and more than Martin Luther is.

The mortality of the soul is scriptural: Ezekiel 18:4 "the soul that sinneth, it shall die." Those who will remain separated from God for all eternity, due to unrepentant sins, hall be dead. Sin is death.
