What a question
I wanted to say “what a great question” but I felt dishonest saying that because I felt it implied I have a clear understanding of the word “ethos” … which I kind of do and kind of don’t 
Personally I am interested in this question outside of the context of the unMonastery - exactly as you presented at - in regard to EdgeRyders itself.
My life experience has instilled in me a very deep suspicion in regard to rituals. I have witnessed too many discrepencies between what the spirit of the ritual is and what actually takes place and comes across from those who participate in it. People say one thing (usually “good intentioned”) but manifest another thing (usually “mal-intentioned”). So I have a deep distrust and disdain toward rituals and ceremonies … at least those that I’ve experienced in my life. As a result I have two rituals in my life - peeing in the morning and breathing through the day.
However I do believe we are in dire need of a kind of spiritual upSkilling … an opening up to that which exists beyon the rational. This comment by [ad-admin] had some clues in it to things that may be worth looking into:
- should we worry about "holding candles and giving false impressions"? if so why? what can we learn from this need abour ourselves, our relationship with those "outside our community"? does indicate an opportunity to do something about it (not necessarily now during LOTE3, but over the 200 years of the unMonastery)?
- why does "rational" trump "superstition"? does "rational" connect us to the earth's wobbles or limit our relationship with them? maybe superstition has a complementary reflection to offer that completes a limited "rational" view?
- why do we assume that "rational" is inherently forward thinking? there's plenty of evidence to refute that. Is this assumption a truth or an escape from other truths we have grown less comfortable living with?
I have very little interest in a pagan ritual I know nothing about with people with whom I have not connected. Pretending (=assuming without connection) we share values, thoughts, ideas and inspirations feels disrespectul towards myself, each other and the magnificent wobbles of the earth or any other expression of nature we may be celebrating. Rituals indoctrinate (consciously and or subconsciously) … and indoctrination should be done with much more care then other forms of education.
I do have plenty of interest in creating a sense of communicable togetherness (ethos?) of EdgeRyders or at least learning what we can from trying to move together in creating such a connection.
