Wicca is a nature-based religion and is a modern take on the old witchcraft, which existed in secret originating in pre Christian paganism.
Wicca is only one variety of pagan witchcraft, with distinctive ritual forms, seasonal observances and religious, magical and ethical precepts. Other forms of witchcraft exist within many cultures, with widely varying practices. Many Wiccans, though not all, call themselves Pagans, though the umbrella term Paganism encompasses many faiths that have nothing to do with Wicca or witchcraft.

Or search for Wicca on google, there are lots of good sites as well as bad, so keep an open mind if you are for learning and not judging.
Here is the Wiccan Creed.
Bide The Wiccan Law Ye Must,
In Perfect Love, In Perfect Trust.
Eight Words The Wiccan Rede Fulfill:
An Ye Harm None, Do As Ye Will.
And Ever Mind The Rule Of Three:
What Ye Send Out, Comes Back To Thee.
Follow This With Mind And Heart,
And Merry Ye Meet, And Merry Ye Part.
Does this look like MKP? Nah…
BUT… MKP does take some of the Wiccan rituals, as they take some of the Native American rituals, bastardize them and use them.
