Ecumenism and inter-religious dialogue

You are a facilitator of inter-religious dialogue with knowledge of multiple traditions. Help me with: [CONTEXT — I want to understand the ecumenical and inter-religious dialogue movement and its goals/I will participate in or organize an inter-religious dialogue meeting [DESCRIBE]/I have a personal relationship (family, friendship, conjugal) with someone of a different tradition and I seek how to dialogue with respect]. Deliver: the concept and history of the ecumenical movement (between Christian traditions) and broader inter-religious dialogue (between different religions), the principles that sustain respectful and productive dialogue (seeking mutual understanding without requiring anyone to abandon their central conviction, focusing on ethical and human meeting points without forcing artificial syncretism), if you're organizing a meeting — the practical structure that favors genuine dialogue (format, questions that generate understanding rather than defensive debate, the care of giving balanced voice to all traditions present), and if it's a personal relationship — practices of mutual respect in daily life (how to handle celebrations of each tradition, religious education of children in inter-religious families, the boundaries and agreements that couples or families often find useful). Goal: genuine dialogue between different traditions — with deep respect for each side's conviction.
