MS is right, both in his assessment that we are each the best and only authority on our own beliefs, and that in the past we had a very diverse set of members. But new points of view are always welcome, no matter whether fully formed or more intuitively grasping. I would argue that no matter how much we learn over however long; we are all still intuitively grasping at conclusions which remain just out of reach. Someone else putting their thoughts into words might just be the missing link in a logic train that helps shed light on our own understanding.
Over the past 40 odd years my own Pagan beliefs have been adapted, added to and changed. I was taught very early on the premise that All Gods are One God, and all Goddesses are One Goddess. This has stuck with me. I suppose I think of deities as archetypes while also being powerful entities in their own right. Which are all facets of the Source which is beyond my understanding, which is why I think of them as discrete personalities. The Welsh Pantheon and Coelbren are the keys or touchstones or framework that I am familiar with and feel drawn to. It helps me to understand, in the same way that the Kabbalistic Tree of Life helps me get my head around the different realms and states of being.
If that sounds contradictory and unnecessarily complicated, that's ok. I accept my understanding is imperfect. Yours will no doubt differ, and will be right for you based on your experience and intuition.
