Freedom and the Captive Mind is a biography of Fr. Gleb Yakunin, the first Orthodox priest to adopt an ecumenical approach to Russian Orthodoxy, earning him the enmity of conservative groups within the Church and gratitude from other religious denominations. Father Yakunin believed the survival of the Church depended on its willingness to reform. When he was suspended, Yakunin continued to fight the system, working to expose the persecution of religious believers in the Soviet Union.

After years of exile, Yakunin entered politics. He was criticized by religious authorities, denounced by nationalist politicians, and excommunicated by the Russian Orthodox Church. As Wallace L. Daniel demonstrates, the letters Yakunin wrote and his revelations about the relationship between the Church hierarchy and the KGB stand as monuments of courage and the determination to reveal the truth about abuses of power and the authoritarian mindset that predominated in both institutions.
