The eastern Church believes that hell or eternal damnation and heaven exist and are the same place, which is being with God, and that the very same divine love (God's uncreated energies) which is a source of bliss and consolation for the righteous (because they love God, His love is heaven for them) is also a source of torment (or a "Lake of Fire") for sinners (because they don't love God, they will feel His love this way).
