Kind of been wondering about this, the Burning Man event seems to attract a lot of leftists, but attracts my interest as it seems to also attract artists and artistic expression, maybe a kind of environmentalism, I don't know. Their main celebration seems to have been a repackaging of the pagan event of burning a wicker man, they burn a big effigy to end the event.
It's kind of ambiguous about being pagan or nonreligious or whatever but I think there are probably plenty of objectionable things that take place that "conservatives" or "Christians" might want to steer clear of. But, I think possibly there are good things that might be adapted in to some alternative new event or incorporated in to existing events.
Any idea about "Christian conservative" alternatives to Burning Man?
perhaps not much is needed to satisfy a Christian, truly
although there have been Christian feasts and festivals throughout history I think
no, not much is needed. The Bible talks about being content with what we already have. Reading that part helps sets the believer at ease with what they've already been given.
Jesus wants us to know Him who died for us, which thousands of lifetimes spent in seeking to know Him more would barely be able to scratch the surface of beginning to know who He is.
