AbstractIn The Pillar and Ground of the Truth Pavel Florensky presents an account of hell, or ‘Gehenna’, that synthesises two seemingly irreconcilable claims: that God will save all people, and that some people will reject God forever. In insisting that both claims are true, and by recasting standard categories of final judgement, purgation and human identity, Florensky produces a novel contribution in contemporary debates about hell and universalism. I begin by surveying his account, then address two key interpretive questions raised by his critics, and conclude by situating his account within modern western conversations.
