I know this wasn't addressed to me, but I had to think about what you said.
I don't meet many people who say they are 100 percent sure they of who they are in their given faith/s. It's more I'm 100 percent committed to a given faith/s. So, for example, I can speak about Catholicism and the love for it and my being part of the Church as if I am still in it. It's a part of my being and soul. I can't take that away.
I can speak about it from experience even though I'm not at all committed to it anymore. It's more of a personal thing. It's like going out with someone and you love him or for me, um, her to death. You dated for years, and then for a good reason, you two had to break it off.
Now, just because you flip from one person to date to the next doesn't negate that you still have love for the first or second person you were with. It also doesn't negate that you still have feelings for this person and to make it more closer to religion, if you were married, then it's even harder to break that marriage even if legally. It's a personal experience not flipping belief and not a dogma.
I know I was confused when
@Saint Frankenstein changed faiths from the what two or three years I've been here
and I know in my personal experience that we have a plethora of beliefs built into our own bodies that to me, it doesn't seem like people chosen one faith, they just chose a faith or morals that they agree with more than others.
I think that's the same with Saint (if I am not mistaken?). There may be a pull to this to that or whatever, but spirituality isn't a social club. It isn't chaos, and it isn't eclectic. It's a solid foundation to which one's other beliefs and practices bounce on. So, for example, my foundation is Buddhism. However, my practices are not only that of The Buddha, I also revere my ancestors through pagan (well, spiritualist, rather) practices.
I remember talking to a Bahai here that said h/she doesn't question h/her belief and never felt a need to. Almost as if this person had no doubts, no use of faith, no challenge thereof, they just live. I find that weird from any person growing on their spiritual walk.
So, anyway, it's confusing, yes; and, that's how it should be. I don't know many people who shop around for faiths, but I know eclectics have a different view on how they choose than someone who literally has a crisis in faith. The former may know what or who they want to worship or revere (whatever) but the latter, it's more of a internal thing. It's something that needs to be worked out between that person and who/whatever they with. Spiritual depression.
I don't know how anyone can call this anything other than spiritual growth. It's normal and healthy.
Nam.
