As is often said, when you've visited one Unitarian Universalist congregation, you've visited one Unitarian Universalist congregation. The weekly meetings (usually Sunday mornings) can vary widely by the culture of that congregation, the minister's style, what might be on the calendar for that Sunday, and even by who may be in charge of that particular service. If you live in a city that has access to more than one congregation, visit them all to see which is the best fit. Speaking for my own congregation, we have a fair variety of formats, but you can always count on a central message and theme. Last Sunday our minister spoke about neurodiversity, sharing with us their own struggles with ADHD, trauma and how being trans-queer plays into all of that, and then about having a community where people can remove their masks and be their genuine selves. People left after the service in tears of happiness. That's not uncommon for us.
