I agree..."worship" is widely understood to imply something that isn't really applicable in a UU context (no matter what the "powers that be" in the UUA say about reclaiming religious terminology).
We can look over every time a Minister says "worship" or refers to "God" or "Jesus" and pretend we didn't hear when he says "prayer" or contort ourselves or define "holy" and "spirit" in a way that does not strike a discord with us...but we would be avoiding the problem, acquiescing to the recent trend of christianization of UUism with our silence. This trend tends to come from the elites in the movement, and especially many key Ministers. You can help by resisting this creeping christianity and help regain the balance that once flourished at the heart of UUism.
