The received wisdom is that the experience of Revolution in recent centuries is inimical to Christianity. It brings in its wake hostility, disruption, and persecution, as one, usually secularising, value system bids to displace a religious one. The Church and Counter-Revolution walk together. But should we be more cautious about this conclusion? Deploying three categories – the dispossessed, the collaborator, the indifferent – the lecture suggests that, amid the upheaval and the suffering, the experience of Revolution can also be creatively purgatory for the Christian Church, bringing about new growth, organisational leanness, and inspirational instances of martyrdom.
