A passage in Gregory of Nyssa' Great Catechism struck me:
"Now, to the pure, freedom from passion is that kindred state, and that in this freedom from passion blessedness consists, admits of no dispute. But as for those whose weaknesses have become inveterate, and to whom no purgation of their defilement has been applied, no mystic water, no invocation of the Divine power, no amendment by repentance, it is absolutely necessary that they should come to be in something proper to their case,—just as the furnace is the proper thing for gold alloyed with dross,—in order that, the vice which has been mixed up in them being melted away after long succeeding ages, their nature may be restored pure again to God. Since, then, there is a cleansing virtue in fire and water, they who by the mystic water have washed away the defilement of their sin have no further need of the other form of purification, while they who have not been admitted to that form of purgation must needs be purified by fire." (chap. XXXV).
Does Gregory here seem to imply that those who have not been purified through baptism somehow must go to some sort of purgatory? This idea seems to be reinforced by the introductory sentence of the following chapter ("For common sense as well as the teaching of Scripture shows that it is impossible for one who has not thoroughly cleansed himself from all the stains arising from evil to be admitted amongst the heavenly company.") Yet I thought that the idea of such purification by fire never developped in the Orthodox world as it did in Catholicism.
