St. Theophylact of Ochrid ca. 1055-1107
A conclusion to be drawn against the Origenists who say that there will be a time when there is an end to hell, that the sinners will be united with the righteous and with God, and thus God will be all in all. Let us hear what Abraham says, that they who would pass from hence to you, or from thence to us, cannot. Therefore, it is impossible for anyone to go from the place apportioned to the righteous to the place of sinners, and likewise, Abraham teaches us, it is impossible to go from the place of punishment to the place of the righteous. And Abraham, I presume, is more trustworthy than Origen. (Explanation of the Gospel According to St. Luke, Chap. 16)
