That form of worship makes sense if you are dependant on those results for survival. But we live in a world where the majority of us depend on being able to make it the super market and having sufficient money to buy groceries for survival. Performing fertility rites in the spring and giving thanks for a good harvest in the fall makes little or no sense and at worst is woefully insincere and self-serving.
Instead of doing something in the hope of obtaining a desired result, the purpose of a ritual in the first place, you are going through empty motions that only serve to make you look important. If you truly desire to honour the natural world, then you need to create a means of doing so that doesn't involve putting yourself ahead of what you worship.
Humility and being humble are two very important parts of worship that Wicca and other New Age faiths seem to disregard. It's all about what I can get from doing this instead of being grateful for what I have received.
Seeing someone call herself a high priestess of something called Wicca, and realizing that she is going to be nattering on about how special they are and what Hallows' Eve means to them, only serves to remind me how far humans have drifted from the real belief that we have things to be grateful for. When did we become so selfish?
