Rituals and openness
Thanks for the explanations! No, I’m not interested to put labels on people. Rather to learn what motivates each single person to do and like the things they do … and that’s really interesting, as everybody is so different.
About sacred and secular: is that even a difference? I always expect that, should I ever get the “full” understanding of reality that I will of course never achieve, it will imply the realization that I live in one reality. Neither sacred nor secular, it’s all part of one world. And “one world” means, no mutually contradicting spaces of knowledge. That’s why I am so insisting about distinguishing facts and form in religious behavior: in order to finally find how, for example, natural sciences and theologic facts are just two parts of the same reality … still struggling with it, and a long way to go, but you may call me a believer if you like 
About Arthur’s remarks on what fits the ‘ethos’ of Edgeryders: I understand and share the worries, and would frame it like this: when including an actual pagan ritual, or in fact any ritual of a fixed belief system, it’s hard to keep up the impression that this space is welcoming everyone, to explore, share and discourse about all kinds of stuff while feeling comfortable. The more closed impression with rituals, even if not intended, seems to come in with the power of imagery and ritualized behavior, which have considerable psychological power and alsofor bystanders, carry the notion of “a mystery, for the initiated”. A ritual is also different from a discourse about a ritual, which I’m comfortable and interested to have here (like now in fact). In a discourse I’m always welcome to contribute my perspective (even if that’s “Let’s dissect rituals with science” 
), while in the actual ritual I’m not …
However, it’s not just as simple. Given that rituals, symbols and imagery are all powerful, it’s of course interesting to experiment with that, and to use them for expressing content (like “celebrating” something). How to do that here and keep being a welcoming place for everyone? It’s my impression that the key is inventing your own imagery and rituals rather than taking over existing ones or merging them into existing belief systems. It communicates “Hey, we made all this up, there’s no deeper meaning. We’re just interested in the social effects.” unMonastery itself would be an example, and seemingly also Bembo’s “Listening to the Ancestors” walk (minus the candles maybe ), and parts of Sunday Assemblies. (And for context, that’s why I asked about a “fully secularized” version before.)
Does the above make sense? (I’m just gathering my thoughts on this on the go … never thought about this before.)
