Inhabiting the Christian–Hindu Threshold presents a disciplined model of interreligious learning shaped by Francis X. D’Sa, SJ. The volume gathers scholars who treat dialogue as a craft: beginning with performance, moving to text, and returning to lived practice. Two anchors guide the method. First, D’Sa’s use of dhvani (resonance) protects layered meaning from premature doctrinal closure. Second, a cosmotheandric horizon (divine–human–cosmic interrelatedness) measures interpretations by the quality of worship, ethics, and shared life they enable. Contributors apply these tools across scripture, theology, education, ecology, business ethics, and pedagogy, offering practical procedures—naming positionality, specifying versions, co-reading with communities, and welcoming counter-voices—that resist extraction, harmonization, and ventriloquy. The result is neither syncretism nor relativism but accountable reciprocity: Christian thinkers learn with Indian categories while Hindu archives are received on their own terms. This book turns aspiration into teachable method and equips classrooms, communities, and civic forums to inhabit thresholds with truth and care.
