Rabbi Abraham Joshua Heschel's theological vision occupies a unique position between modernist and postmodernist religious thought, offering vital insights for contemporary Christian-Jewish dialogue. Through a comparative analysis, this research explores how Heschel's contemplative epistemology, prophetic understanding of history, and interfaith engagement continue to resonate with Christian scholars navigating postmodern challenges to traditional theology. His poetic theological language, which emphasizes divine pathos and prophetic consciousness, transcends subject-object dichotomies while addressing both modernist historical concerns and postmodernist appreciation for metaphorical discourse. The investigation reveals that Heschel's enduring influence among Christian educators stems from three key elements: his accessible biblical scholarship, his proven framework for interfaith dialogue, and his seamless integration of contemplative spirituality with social justice activism. As traditional theological methodologies face postmodern critiques of unity, origin, and transcendence, Heschel's work provides a valuable "liminal" perspective that bridges religious traditions and contemporary philosophical movements, suggesting his continued relevance for future theological discourse.
