In the world of religion, where the idea of faith often reigns supreme, the notion of reason and inquiry can sometimes seem out of place. But for the Unitarian Universalist tradition, which has its roots in Humanism, these concepts are not only welcome, but celebrated. Humanism, with its focus on reason, ethics, and social justice, has long been a part of Unitarian Universalism, and has helped to shape its inclusive and open-minded approach to spirituality. By exploring the history and philosophy of Humanism within Unitarian Universalism, we can gain a deeper understanding of this vibrant and diverse religious community and the values that it holds dear.
