What are my beliefs cled as?

I don't believe in the Christian idea of God, although I do believe in a higher power of some kind. I was brought up Catholic, but I no longer practise, I disagree strongly with the fundamentals of Catholicism and I don't believe in organised religion. I wouldn't say I'm atheist, as I do believe in a higher power. So what am I? Agnostic? Thanks to all who answer.
