Luminescence is a holiday that celebrates principles and values central to the UU faith, such as peace, justice, compassion, and the continuous pursuit of truth.

Originating in 2007 by UU or SCV to foster a shared sense of identity and spiritual renewal within UU communities, the celebration incorporates symbolic rituals like lighting five candles, representing inner light, shared sparks of inspiration, and the enduring nature of illumination that grows as it is shared. These rituals emphasize personal growth, collective well-being, and the UU commitment to justice and inclusivity.

This holiday stands apart by embracing diversity and openness while drawing on UU traditions. It highlights the faith’s dedication to universal principles rather than specific religious doctrines, making it accessible to people from various beliefs. Luminescence also encourages reflection and renewal, urging participants to reaffirm their commitment to creating a better world. As part of an effort to establish distinctive holidays, it enriches the liturgical calendar with celebrations that uniquely honor UU values.
