This final lecture explores how Free Religion evolved from a 19th-century German movement into a global force for liberal religious values, shaping and being shaped by the International Association for Religious Freedom (IARF) and other interfaith initiatives. We will trace its journey from local congregations to a transnational network committed to freedom of conscience, social justice, and interreligious understanding.

Key themes include:

• The foundation of the IARF (1900) and Free Religion’s role in its early development, including collaborations with Unitarians, Universalists, and other liberal religious groups.

• The impact of globalization and migration on Free Religion, as its principles of tolerance, reason, and human dignity resonated across cultures and continents.

• Case studies of international engagement, such as the Offenbach congregation’s interfaith initiatives (e.g., the "Prayer of Religions") and its work with refugees, LGBTQ+ communities, and feminist movements.

• The challenges and opportunities of Free Religion in the 21st century, including its response to secularization, religious extremism, and climate change, and its vision for a just, pluralistic, and sustainable world.

By the end of this lecture, you will understand how Free Religion’s local roots and global reach have made it a unique and enduring voice in the modern religious landscape. You will also reflect on its future role in fostering dialogue, justice, and spiritual freedom in an increasingly interconnected world.
