The Teachers of the Eastern Orthodox Church, having Holy Scripture as their foundation, teach that those who die in the Lord go to a place of rest, according to the statement in the Apocalypse: "Blessed are the dead who die in the Lord from henceforth. Yea, saith the Spirit, that they may rest from their labors; and their works do follow them" (Revelation 14:13). This place of rest is viewed as spiritual Paradise, where the souls of those who have died in the Lord, the souls of the righteous, enjoy the blessings of rest, while awaiting the day of rewarding and the prize of the high calling of God in Christ Jesus...
About the sinners, they teach that their souls go down to Hades, where there is suffering, sorrow, and groaning, awaiting the dreadful day of the Judgment.
The Fathers of the Orthodox Church do not admit the existence of another place, intermediate between Paradise and Hades, as such a place is not mentioned in Holy Scripture.
After the end of the General Judgment, the Righteous Judge (God) will declare the decision both to the righteous and to the sinners. To the righteous He will say: "Come, ye blessed of my Father, inherit the Kingdom prepared for you from the foundation of the world;" while to the sinners He will say: "Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels." And these will go away to eternal hades, while the righteous will go to eternal life. This retribution after the General Judgment will be complete, final, and definitive. It will complete, because it is not the soul alone, as the Partial Judgment of man after death, but the soul together with the body, that will receive what is deserved. It will be final, because it will be enduring and not temporary like that at Partial Judgment. And it will be definitive, because both for the righteous and for the sinners it will be unalterable and eternal.
