1~ What is the difference between the Occult and Wicca? The Occult is relating to "supernatural" powers or knowledge, Wicca is catergorized under Occult.
2~ is the God worshipped in Wicca, the Christian God? I'm sure this is one you'll get very different answers for, but I believe that all of the dieties prayed to from all of the different religions are one in the same...only called by different names. While researching the different Gods you will find that their stories of origins & myths surrounding them are all very similar to each other.
3~ Who is the Goddess, as the Christian God says to worship no other God's or idol before him? The Goddess is the feminine half of the God. In Wicca, male & female are equal. The masculine & feminine are to be equally balanced. The God is metaphorically split into two equal halves, both as important as the other.
4~Can anyone study to be a witch/warlock? I say yes, some say you need to be born into it, but if you seem to have interest in learning about becoming one, then there must be a good reason for it.
5~What exactly is a warlock? A male witch? "Warlock" is very rarely used for male witches, from the Old Norse var lokkur, "spirit song" . Some will tell you that a male witch is called a witch, & that a warlock is someone who was banned from the coven.
6~ Are all witches phsyic? (yes I know I can't spell that.) Not only are all witches psychic, but all PEOPLE are. You are born with inherent psychic abilities...it is only when doubt of what you are experiencing is continually put upon you, do you start to push these abilities aside, making it more difficult to re-obtain once you may decide to take them up again.
7~Can you be Wiccan and not a witch? Oh, there are some Wiccans who dislike the phrase "witch" because of the negative portrayal of them in stories & movies, "Witch" comes from the Anglo-Saxon wicce (witch), derived from an Indo-European root word meaning "to bend" or "change". It may also be related to the Old Norse vitki (wizard), derived from root words meaning "wise one" or "seer."
8~Do witches speak latin or witchen? LOL I'm sure some do!...lol I study several different languages. Some may chant their spells in Latin or other languages, but everyone has their own individual ways of doing things.
9~Can anyone do a spell? Yes...although some will be more powerful than others, it just depends on your goal & the time & energy & knowledge that you put into it.
10~ Your energies have to be completely focused to make a spell work, right? YES...and that is exactly what a spell is...focusing your energies on manifesting into your desire.
11~Is it okay to worship the Christan God and believe in witchcraft? Sure...he doesn't just belong to the Christians after all...he is in each & every one of us.
12~Are some witches evil? And do they get their powers from Satan? (NOT ALL, just some?) As with any group of people, there are always going to be a few bad apples. There are some people who learn about witchcraft to only do ill against others. Wiccans strictly believe that whatever you do will come back to you 3 times (some even believe more than 3), so obviously you would want to do good so you get good coming back instead of bad, as to adhere to the rede, which at the end states...."an ye harm none, do what ye will".
As for Satan, the Pagan God-image was bent into one to be feared as evil while they were trying to convert Pagans to Christianity. Wiccans do not believe in Satan because we know he does not exist.
Good luck on your screenplay! I'd love to read it sometime. I have always wanted to make a movie, but of course you need money to do that...LOLOL But I have plans for a low-budget music video, so that's a start in the right direction. I hope these answers help...if you have any more questions post away!
