Radical Then, Radical Now by Jonathan Sacks

The Future of Faith in a Secular Age

A concise meditation contrasting the morally rooted revolts of ancient religious prophets with modern political radicalism: the former sought justice within ethical limits, protecting the vulnerable and restraining power, while the latter too often abandons moral constraints and becomes violent or totalizing. The book warns that ideals unmoored from ethical responsibility lead to oppression and argues for a renewed form of radicalism—one that preserves the prophetic impulse to challenge injustice but does so through humility, pluralism, institutions, and nonviolent, rights-respecting reform.
