I think it's a question I haven't asked myself, or at least I haven't looked too hard for an answer. I think initially, it was just that I hadn't ever really connected to the religion I grew up in and I felt as though I needed to look at what else was out there in order to truly say that I believed what I said I did. So I was hoping by looking outside that religion I could either 1. Develop a faith in God that I never think I had to begin with. or 2. Arrive at some version of the truth that I could be at peace with. That is to say, I would find truth for myself. And by "truth" I guess I mean an answer for myself to the questions "why are we?," and "what are we?," and "what happens beyond death?"
I think that last question is probably driven more by fear than curiosity.
I think it is funny though....I think at some point I would have said that losing my faith in Christianity would have affected me negatively; like I would lose hope. But I guess I never really had that to begin with, and sometimes I feel not having a clear answer to my questions has given me more of a purpose. I feel as though if I'm not questioning why we exist, then what am I doing? I guess that's my answer: I hope to find answers, but some of my purpose in seeking is that I find purpose in seeking. And asking other people about what they found is just part of that.
I think the crisis at this point is more because like 95% of my family and friends are Christian, if not conservative Christian they are Christian in some form. I've only told my closest friends and my sister that I am not anymore. The spiritual isolation comes from not having anyone to dialogue with about it. Hence, I am here.
I haven't had a chance to properly read this thread and absorb what people are saying but i caught sight quickly there of someone saying something along the lines of there being many paths to God
The work of Joseph campbell explores the idea of all the worlds religions being different expressions of the same hero journey. In each religion the hero is different but their quest is essentially the same
Joseph does not advocate that you worship the hero of the religion but rather that you yourself become the hero in your own spiritual journey
he speaks of archetypal images that appear to people on this journey which mark the passage of a person along the path. The indigenous cultures of all people around the world have these myths that contain these archetypal images so people have been aware of this ephemeral process for many thousands of years
Some people have some negative words to say about christianity and some of those people have a materialist ideology that underlies their opinions.
My own view of christianity is that at some point some people, lets call them the priest caste, decided that they could gain more power by removing people from direct religious experience and instead placing themselves as an intermediary between people and the divine
Prior to this people would have seen each other as expressions of the same divine source who are each living out their own individual experience in this reality as a ***fill in the gap***....christian, muslim, jew, atheist, man, woman, gay person, trans, whatever
Each person could then if they were so inclined seek a religious connection to their source as the divine is essentially already present within them
However I think the priest caste said to people that God is not within but is instead without and from that time onwards people started revering outer deities that were packaged for them by the priests. Because people stopped seeing the divine in themselves and everyone else they were then easily divided into competing factions and also by placing themselves as the messengers of the external god the priests then gave themselves a privileged place of power
Why christianity is perhaps failing is because it has moved away from its roots of personal spiritual connection with the divine which is what its early desert fathers and celtic ascetics were trying to do and instead is selling people absolution from their sins as well as viewpoints that come from the priests themselves rather than from any higher source
So if you are going to seek your authentic self and try and pursue your own hero journey you have to cut loose from the priest caste and start listening to an internal voice
Yes, even in the toilet.
