There are a lot of people out there seeking their spirituality. When they find it, they approach it in many different ways.
Some people are content simply to worship, and that is wonderful.
There is most certainly nothing wrong with that. These people have their personal and private relationship with Deity and are perfectly content to follow that Path. Others feel the call toward something stronger. They feel the Hand of the Goddess upon them, calling them to serve as clergy. You're an ordained minister of that particular Path.
