Now collected into one document, a PDF, are quotations from Orthodox Patristic writers on Hell. At the end of the document there are some quotes from more contemporary Orthodox theologians also on Hell. You can find that document at The Fathers on Hell (PDF). Many thanks to Fr. Silviu Bunta who gathered most of the quotes from the Fathers. It is a work in progress and may be updated from time to time.
Many of these quotes deal with how the Fathers conceived of Hell not as a place of eternal torment, but rather as a state of being in the presence of God. For those who have no love for God, being fully present in His love burns, but it is still being burned by the presence of God.
