This presentation explores three essential dimensions, free dialogue, sustainability, and transformative education, and their specific manifestations: interreligious dialogue, water sustainability, and values-based education. These dimensions are critical for addressing global challenges such as polarization, environmental degradation, and inequities. By examining their theoretical foundations, practical applications, and interdependence, the article demonstrates how their integration fosters justice, peace, and societal transformation. Implications for practice and for societal impacts are discussed, emphasizing the need for a holistic approach. This presentation is realted of a research study for an Erasmus+ project on sustainability (water), interreligious dialogue, and teaching.
