It's got three parts to the Baha'i Feast... a devotional part, a business part and a social part. Some of the Baha'is I knew didn't even like the business part. But I think that's why it's for Baha'i only.
I've mentioned this story before... Now I have been with a Baha'i friend at an Ecumenical gathering. One was held at a Reformed Jewish Synagogue. The Christian groups that participated were all from liberal Churches. I don't remember any other religions that were there, except for the Baha'is. My friend and sometimes one other were the only Baha'is that attended the regular meetings. This meeting was a bigger event where speakers from each group went up front to say a few words... that is until the Baha'i lady went up.
The local Baha'i leaders, that never went to any of the regular meetings, thought this was a great opportunity to tell the captive audience about the Baha'i "Peace Statement". They picked a prominent Baha'i to go up there and not say nice things about how wonderful it is that they can all get together and get along, but they wanted her to go up there and read the Peace Statement. It was a great big flop. After a couple of pages of reading, she could tell the group was bored to death, and she stopped.
I think a guy like LH wouldn't do that. He'd probably be more like my friend that attends the regular meetings and just tries to be friends with the other people there... and not try to cram the Baha'i Faith down their throats. Tony sounds like that kind of guy also. He says he goes to Church meetings in his town. And that's just swell, but I think at some point any Baha'i is going to try and "teach" the Faith to those people.
So, what is the purpose of going to these meetings? For a Baha'i, I think it is to find potential converts.
