Book excerpt: In The Religious Concordance: Nicholas of Cusa and Christian-Muslim Dialogue, Joshua Hollmann examines Nicholas of Cusa’s unique Christocentric approach to Islam. While many late medieval Christians responded to the fall of Constantinople with polemic, Nicholas of Cusa wrote a peaceful dialogue (De pace fidei) between Christians and Muslims as synthesis of religious concordance through the person and work of Jesus Christ. Nicholas of Cusa’s Christ-centered dialogue with Muslims sheds further light on his broader Christ centered theology over his entire career as philosopher and theologian. Drawing upon Nicholas of Cusa’s philosophical foundations for religious dialogue and peace, Joshua Hollmann convincingly proves that Cusa constructively understands religious diversity through the concordance of religion as centred in Christ.
