Parental Consent
I suppose that being part of an "outside the mainstream" group opens one up for this type of thing, but I continue to hope and wish that common sense and perhaps intelligence might overcome. Unfortunately, my desires do not always win out.
It truly makes me wonder when children expect adults to assist them in freaking out their parents. The under 18 crowd who want adults to help them "hide their faith" from their parents totally confuse me. I suppose that's only fair because apparently I confuse them when I tell them that the faith will still be here if they wait to practice it until they are of age.
Many of those who insist on shoving their newfound faith in their parents' faces, almost daring them to "do something" about it. Sometimes, it's a scream for attention. Sometimes, Wicca is the next attempt in a series of means to annoy parents after the child has already tried being goth, dying their hair purple, piercing their tongues or eyebrows, etc. etc. No, this is definitely not ALL of the children who are interested in Wicca. And yes, it is very difficult to be a child living with parents who are not "religiously hip." It's very difficult to be a child living with parents who are not "hip" in general. However, sometimes there is a price to be paid for living in the house and being supported by Mom and Dad.
I do not personally advocate hiding your faith from your parents. However, if your parents have forbidden you to practice Wicca or Paganism or whatever, fighting with them about it is only going to serve to drive a wedge between you that you may not care about now, but you definitely will care in later years. You can always wait until you move out, and then it won't be their business anymore. Although they may still pray for your soul, they will no longer be in control of your day to day life.
Please keep in mind that parental consent is a very "big deal" for many of us in the Pagan community. Adults who mentor or assist those under 18 with their faith can be held liable in court (depending on state law, of course) if the parents decide that religious instruction is being provided without their consent. This is why so many hesitate before taking on teen students. It can definitely be a significant issue.
So, my advice is, if your parents don't agree with your choice of religion - wait a few years. The Goddess will still be there to welcome you.
