Religious? or Spiritual?

I define myself as a "Secular Pagan". I'm Italian, and as you know, centuries of Christianity have destroyed my ancient culture, how ever, I consider the ancient Greek-Roman culture my only spiritual roots. I think that atheists too can be "spiritual", they have a sort of "secular soul", a sort of soul that containes every emotion, feeling, thought, experience of ours and that can be defined a "spiritual" one. Not only religious people have a soul, not only people who belong to a religion can experience the spirituality, every human being can experience it. That's what I think....

I am an atheist. I cannot be spiritual, in any meaning that I can associate with the word. I am extremely materialist. Any other doubts? If you have, I will be glad to answer, and just to make it clear, the answers applies only to me.
