Eastern Catholic churches affirm the reality of hell as the state of eternal separation from God for those who definitively reject him. This is consistent with the defined teaching of the Catholic Church. Hell is not understood primarily as a place of physical torment imposed by God, but as the experiential consequence of a soul's final refusal of divine love.

Within Eastern theology, there is a rich tradition of reflection on God's unconditional love and mercy, and many Eastern writers—including St. Isaac of Nineveh—have expressed hope that God's love might ultimately reach all souls. However, Eastern Catholic churches do not formally teach universalism, and the existence of hell as a real possibility for those who reject God is maintained. The Eastern liturgical tradition includes intense prayers for the deceased and commemorations of the departed, reflecting the belief that prayer for the dead is meaningful.
