On Purgatory

Synod of Constantinople 1772

We the godly, following the truth and turning away from such innovations, confess and accept two places for the souls of the dead, Paradise and Hades, for the righteous and sinners, as the Holy Scripture teaches us. We do not accept a third place, a Purgatory, by any means, since neither Scripture nor the Holy Fathers have taught us any such thing. However, we believe these two places have many abodes…
None of the teachers of the Church have handed down or taught such a Purgatory, but they all speak of one single place of punishment, Hades, just as they teach about one luminous and bright place, Paradise. But both the souls of the holy and the righteous go indisputably to Paradise and those of the sinners go to Hades, of whom the profane and those who have sinned unforgivably are punished forever and those who have offended forgivably and moderately hope to gain freedom through the unspeakable mercy of God. For on behalf of such souls, that is of the moderately and forgivably sinful, there are in the Church prayers, supplications, liturgies, as well as memorial services and almsgiving, that those souls may receive favour and comfort. Thus when the Church prays for the souls of those who are lying asleep, we hope there will be comfort for them from God, but not through fire and Purgatory, but through divine love for mankind, whereby the infinite goodness of God is seen.
