They are definitely not. I had to attend a Unitarian funeral for a federal judge this summer as part of a job. It was held at one of their pagan temples which was adorned with the gay flag and that Black Lives Matter posters (despite almost all the congregants being white or Asian). Pretty much they are like liberalism made into a religion. A bunch of sweet kumbaya type nonsense as a façade to their newer age pagan cult centered around humanism and secularism as a handy bandaid that appears nice, but it is really rotten masking just how totally devoid their cult is of the truth of the Only True God.
To not totally poop on their pagan parade in fairness, I dislike funerals, but this wasn't a bad funeral service though since there was no dead body and it wasn't so gloomy. They pretty much played her favorite 60s folk songs and let her family, co-workers, and friends give a little speech about her life. Which I thought was actually a nice touch as one that does not like funerals. My company rented out and operated a projector for them and they had some interesting slide show stuff of her life and works as a federal judge, and in her younger years as an activist in the cause of helping Nelson Mandela come into power.
What stood out to me the most was their pagan priest, I assume the equivalent to a Christian minister or preacher, in the middle of the ceremony he mentioned how she did not believe in God and did not believe in the resurrection and so he wasn't going to contradict her wishes that after death she just be dead. There was an awkward pause, and then they just kept going with it. I couldn't help but notice how odd it was to me and couldn't help but think that she is probably not in a great place for the rest of eternity for turning her back on the Only Savior, Lord Jesus.
