In other words we must be willing to put faith in the divine before what is logical or natural.
This forum has some injunctions about saying definitively whether a practice is or isn't religious but seems amicable to the idea of using real-world examples to discuss what the word 'religion' means. This post continues in that spirit.
I don't believe that we'll get anything like consensus on the question, but here are some key things I look for to recognise religion:
- A notion of the sacred (though not necessarily the divine)
- A received mythic tradition that includes lore and/or ritual
- A cultural foundation, by which I mean people with common ground setting aside differences and make sacrifices to propagate values and beliefs
- A sense of permeation throughout all aspects of one's public and private life
There are certainly beliefs and activities that don't meet all those criteria but which I'd still consider spiritual.
There are also some beliefs and activities that come close but don't quite meet all those criteria. For a personal example, some branches of Aikido have a received mythic and ritual tradition, a strong cultural foundation and a permeation through public and private life, but lack much of a sacred element. Those branches I'd call a Way or Tao. Other branches of Aikido include outright worship (e.g. of leaders, places and/or weaponry) and those I'd call a religion -- though as far as I know, it's not generally recognised in that way.
Back to the original topic, the Trekky fandom I've seen seems to be strong on (e.g.) mythic tradition, and some more devoted Trekky fans may permeate Trekkiness through public and private life. What I haven't seen is a common cultural thread of life-beliefs, or any emergent sense of the sacred.
So what's 'sacred' mean then? I think that it has to do with taboos. Sacred items are those set apart. They have different rules both in how we think and how we act about them.
As far as I know there's no Trekky sub-culture with strong taboos. Over-all, Trekky fan culture seems to even enjoy breaking the default taboos of its own mythos, as the range of Trekky
slash-fic illustrates. More than anything, that makes it look secular to me, rather than sectarian.
