Unitarians are not Christians and don’t even claim to be. I went to one “service” back in the days when I was lost and they played Arlo Guthrie songs and the sermon was on Socialism. I couldn’t get out of there fast enough.
Oh man, the one Unitarian service I have attended was on UN day and it was like the high priestess of fire and water was celebrating a mass for global government.
Creepy. But the pews were absolutely packed with families.
