Through the centuries, marginalized Christian renewal movements have challenged the status quo of the religious establishment, often at great cost. These nonmainstream religious movements generally receive little attention in standard introductions, but Let Truth Prevail tells their story, surveying the history, beliefs, and practices of various medieval and post-Reformation European renewal movements:

17th-century German Pietists 

18th-century Scottish restoration movements

Hussites

Hutterites

Magisterial Protestants and Catholics

Mennonites

The Moravian Brethren

The Schwarzenau Brethren

Swiss Brethren

Taborites

The Unity of the Brethren

Waldensians

Allen Diles classifies these groups as restoration movements, calling attention to their enduring legacies. Each reacted against perceived corruptions in the church and sought to renew faithfulness to God’s truth and his intended ideals as they applied Scripture to their historical context. 

Though Let Truth Prevail demonstrates the strengths of these renewal movements, the book also considers their limitations. Current readers can challenge their own self-understanding of history, God, faith, Scripture, and the practice of the Christian way by reflecting on these marginalized believers.
