If by “Church” you mean a place where people bend down to follow the word from a higher authority, then no, Unitarian Universalists do not belong to a church.
If by “Faith” you mean firm belief and adherence to traditional doctrines, then no, Unitarian Universalism is not a faith.
If by “Religion” you mean scrupulous conformity to a system of beliefs, then no, Unitarian Universalism is not a religion.
Then again…
If by “Church”, you mean a safe place where you can be yourself and bring your loved ones to find support and meaning in facing the joys and struggles of life, then welcome to our church.
If by “Faith” you mean belief in the inherent goodness of all people and the confidence that we can work together to make this world a better place, then welcome to our faith.
If by “Religion” you mean a way of life drawing inspiration and guidance from many sources, engaging your heart, mind, and spirit in a lifelong journey toward wholeness then welcome to our religion.
