A friend Mimi L Thompson who is a biblical scholar studying original works in Latin Greek & Hebrew sent me this on the subject of St Gregory and the Highway to Hell
"Yep, he absolutely believes in universal salvation (ie the salvation of everyone, including sinners and the devil). Hell does not exist eternally. Main ref is ‘On the Soul and the Resurrection’, in which Gregory holds a death-bed discourse with his sister, Macrina.
’Then a universal feast will be kept around the Deity ... and one and the same banquet will be spread for all, with no differences cutting off any rational creature from an equal participation in it’ (de anima et resurrectione 461).
Similar remarks are made a bit earlier, specifically with reference to those in hell :
‘When evil shall have someday been annihilated, nothing shall be left outside the world of goodness, but even from evil spirits shall rise the confession of Christ’s majesty.’ (de anima 444).
Moreover, SGN’s constant insistence that the pains of hell are purgative and purifying – not punitive – strongly suggest that hell is not eternal but that everyone will, one day, be sufficiently purified to enter heaven. Gregory does not think that all will be saved simultaneously: many will have to endure varying lengths of punishment after death."
