Didn't read the other posts, just wanted to throw in my 2cents...
The communal aspect of spirituality does not have to be religion.
A religion is an organized set of ..rules, you could say, on how why & who to worship.
In order to enjoy communal spirituality one does not HAVE to take part in a religion.
I would first say that religions are moral structures created by humans for..many reasons. Religion first served to bring spiritually like minded people together but were soon overtaken by groups and individuals seeking to gain power for themselves. By manipulating other humans' spiritual & moral ideals they exert control over their group and lead the group away from a spiritual path to one rooted in egotistical motives. Now I'm not saying that christianity/islam/insertrandomreligonhere's ideals are necessarily wrong, I'm just saying that humans control religon mostly and usually to gain personal power so the whole system is not so much spirituality based its just controlling.
A better way to grow spiritually is for one to follow their own paths & ideals that explain the balance of the universe in a way they can personally relate to. This would be an example of what you see as Fi based but my argument is that both individual and communal spirituality is important for the individual, and for humanity as a whole.
Change must start on a individual level so individual spirituality is important. (Fi)
Universal truths must be shared with others in order to benefit humanity as a whole so communal spirituality is equally important. (Fe)
Perhaps Fi's are better at personal spiritual journeying, and Fe's are naturally good at spreading and sharing the things Fi types find in their journeys.
It's like yingyang, we have to work together or there isn't balance.
