Re:
- Is there some weird, secular, temple-like setting were one might have a funeral, without Jesus, but enough of a spiritual vibe that his family is fooled into thinking he had religion? ... Some place in artistic Somerville?

This place on College Ave. comes to mind -- built as a Unitarian church, later a Masonic temple, now a place full of art. Concerts and yoga classes are held there. I do not know whether it is possible to rent it for a memorial service. Someone made this blog post about it yesterday.
