Not a Mason, but yes, that's my take. Lodges provide the essential community functions and the recognition of a "universal brotherhood", without requiring any specific theological pronouncements (other than a basic acknowledgement that a "higher power" exists, which is vague enough to allow anyone). This allows virtually everyone in the community the ability to join and work together, more-or-less regardless of individual background or tradition.
Historically, secular fraternities like the Freemasons played a big role in keeping mixed-denomination communities communal, instead of fracturing off into hard, non-fluid segments. I would conjecture that we owe a lot of our cultural religious tolerance to the foundations of trust and community laid in the Masonic lodges of yore.
IMO it's a shame that these groups are not very widely established anymore (at least among "younger" people, who are now becoming "older" people). These fraternities do a great deal to help adults, families, and whole communities.
The only reason I haven't personally seriously inquired into joining such a group is that I'm already in a very active church community that covers most of the Masonic functions, and I have enough trouble just keeping up with that. I'd miss too many lodge meetings, etc.
For anyone who is floating or looking for a consistent community to anchor against, that will be there as an instant community even if you move around, Freemasonry or similar orgs are really worth investigating.
