For a while, I tried to think of myself as "spiritual but not religious". I think what I was trying to say was that I had a sense of wonder and awe, but I felt that religious institutions could be destructive and harmful.
But recently, I have started to think of myself as "religious, but not spiritual". In this, I am saying that I think being in community with people who share my values is important. And I think ritual is meaningful and significant in my life. But I don't hold belief in any specific deity any longer. Oh, I have a sense of wonder. I have a profound sense of the sacred. And I believe there are higher powers than myself (love, justice, to name two) at work in the world. But god? I don't disbelieve. But I have enough doubt to keep questioning. (I used to say that my faith was in my questions. I don't know what that means anymore.)
Having said that, I do feel that religious belief, specifically belief in God, CAN give people much meaning, strength, and hope. I see it every day in my job as a chaplain. And it can be a great motivating force to work for justice and peace in the world. I also know that participating in ritual, even if I don't believe that ritual creates an ontological change in the world or myself, can help to connect me to something bigger than myself, namely community.
I still think that religious institutions can extremely damaging and hurtful, both to individuals (I count myself among the wounded) and to communities and societies. And religious belief can give people and peoples justification for perpetuating injustice and oppression. But I also know it can be a positive and healing force in our world. And while I may not personally have a spiritual connection with any deity, I do feel as if my religious connections provide me with strength, support, nourishment, and hope.
