I am an Alexandrian High Priestess. My own credentials, lineage and personal Pagan history have already been laid out in my Wizzography.
This status means that I've long been in a position to welcome newcomers into Wicca. But for every person to whom I have administered the Five-fold Kiss, there were many more whom I turned away. This path was, in my opinion, not the correct one for them.
Wiccans are not in the business of evangelism. The growth of our religion does not depend upon numbers. Neither is it an elitist club. As I've already stated, self-initiation exists for those who disagree with my evaluation, as do other covens and other practitioners. I am not the final judge and jury concerning other people's spirituality, only my own.
By far the most common action that I've taken is helping disenfranchised Christians find their God again. You did read that correctly. As a Wiccan High Priestess, I've returned significantly more angry and upset Christians back into the arms of Jesus Christ, than I've welcomed into Wicca.
This once earned me the ire of a parish priest, who furiously told me never to speak with any one of his flock again. I politely informed him that if he was doing his job, then I wouldn't have to do it for him. A week later, after he'd learned what I'd actually said to the young lady in question, he sought me out and apologized. I had helped her rediscover the beauty and peace in her own religion.
Which brings me nicely to the major reason that I'll turn people away. They already have a religion, but it's disappointed them in some way. If they're passionate enough about that perceived betrayal, then they are still part of that path in their heart and mind. Wicca is not there for religious rebound nor revenge against a denomination or deity.
The second biggest no-no for me are those people who are lured here by the promise of spells. They are individuals prepared to use witchcraft to manipulate others. Despite the tabloid headlines and lurid advertisements, Wiccans are not here to make the object of your desire fancy you; nor will we attempt to magically brainwash your boss into giving you a promotion.
An automatic rejection will follow for those whom I believe to be unable to exercise their own judgement on the matter. I would never initiate a baby (or indeed any minor), someone who is unconscious nor any person who appears to be seeking a Wiccan path under duress.
The primary thing that I will look for in an initiate is that Wiccan spirit. If everything in them is screaming, 'I am a witch', then who am I to argue with that?
