Карантин. Фантастическая повесть

The main character, Alexander Dahl, is one of the crew members of a spaceship sent to search for intelligent life in the Universe. However, before making contact with the discovered civilization, Alexander must undergo Quarantine: relive lost memories and see... them in a new light.
— Father Alexander! How far does God's Love and mercy extend to man?
— Throughout the universe and beyond our earthly existence, in the space of Eternity. Otherwise, for example, our prayers for the deceased would be pointless, as what is the use of asking God for a posthumous change in the fate of a sinful soul and granting it blissful rest with the saints if such a possibility were not real? In Holy Tradition, there are many examples where the fate of those prayed for has changed in Eternity due to the prayers of righteous people. And a person's fate can change only as a result of changing the state of his soul, under the influence of the divine power of the grace of the All-Holy Spirit of God, capable of producing in the human soul "metanoia" — repentance.
— So, the process of repentance — "metanoia" — the transformation of the human soul can continue even in Eternity?
— Christ answered in such cases: "You have said it!"
