“The nature of evil shall, at length, be wholly exterminated, and divine, immortal goodness embrace within itself every rational creature; so that of all who were made by God, not one shall be excluded from his kingdom. All the viciousness, that like a corrupt matter is mingled in things, shall be dissolved and consumed in the furnace of purgatorial fire; and everything that had its origin from God shall be restored to its pristine state of purity.”
– Gregory of Nyssa (332-398 AD)
