Data from various studies, including those from academic institutions and public health organisations, supports the idea that regular church attendance helps reduce loneliness by fostering social connections, support networks, and a sense of community.

5. there are plenty more...
also if you allow anecdotal data:
I have been going to a church half a year now, and the sense of community is amazing, made new friends and know more people I could dream of. So there is a way, there is a light. Never felt lonely again since.
Got better connections through improv acting and role-playing game.
YMMV
Promoting church attendance might help, but so would any number of group activities the issue is why that stuff is in decline not that stuff not working.
Unfortunately, it is gut-wrenching for me to be in church. I feel terrible, because I simply don't believe any of it. To stand there and be phony and pretend to love and believe in Jesus just kills me.
The whole point is that they're not doing that, not that they can't or that its really hard to do.
Correlation does not establish causation. Regular church attendance dominantly occurs among people who have shared values (clustered around what the church teaches); that doesn't imply that an outsider can just choose to fit in.
