Book examines Christian mysticism through lens of communion with Christ
A new work by Haruo Kaneko explores Christian mystical thought across nearly two millennia, tracing how believers have understood their spiritual union with Christ from New Testament times to the modern era. The book, titled "The Mystery of Coexistence," presents approximately forty mystical thinkers arranged chronologically, with each figure's life and distinctive ideas summarized concisely.
Kaneko emphasizes in the book's opening that the mystical thought under examination is fundamentally personal mysticism arising from fellowship and unity with Christ, rooted in faith in Christ himself. He describes this as a transformation through coexistence with Christ, which he identifies as the source of human life and vitality. The author stresses that this personal mysticism, grounded in communion with Christ through faith, represents a consistent thread running through Christian intellectual history.
Kaneko traces this mystical tradition from Paul's foundational concept of being "in Christ" through Bernard's development of bridal mysticism, which influenced the Protestant Reformation. He identifies Martin Luther as a pivotal figure in developing the mystery of coexistence, arguing that Luther's mystical thought was grounded in fellowship with Christ through faith and embodied the principle of dying to self while living for others. This tradition, Kaneko argues, flowed into the thinking of pastors who guided the modern Japanese church, particularly Masahisa Uemura.
The author situates his work within contemporary concerns. Writing eighty years after Japan's defeat in World War II, Kaneko observes that while many have strived to act autonomously, autonomy has gradually transformed into self-assertion. He contends that the present age requires a fundamental shift from autonomy to cooperative living and coexistence. Uemura, Kaneko notes, recognized the danger of modern people falling into egotism and self-assertion, warning that the enlargement of the ego causes people to lose sight of God's image and weaken their conscience.
Through examining the development of Christian mysticism, Kaneko invites readers to reflect on their own faith and discover the joy of living together with Christ.
