A purifying bath
A pentacle on a string or a necklace, ring or similar thing
This can be done within a cast circle or not.
First purify your body with a bath or shower, concentrating on putting the past behind you.
Stand firm to the ground, holding the pentacle in both hands and showing it to the sun.
"I am (your name) I have been shown the Five points and the Way, and choose to live by life by the Wiccan Rede and the Greater Law it represents. In my hand I hold the pentacle, symbol of the Elements, Earth, Air, Fire, Water and Spirit. Five laws I have been shown, and by the Five I choose to live. I am aware of my actions and I take responsibility for what I've done and what I shall do.
(Optional: "To show this new Self, I have taken a new name, __________, which is what I shall be named in The eyes of the Gods and wherever else your name will be used, including "in the eyes of the Wicca, Henceforth, I am no longer (real name) I am (new craft name) of The Wicca. So Mote It Be!)
I consecrate this pentacle with the power of The Sun and the Hidden Moon, and don it knowing the value and depth of it's meaning. Blessed be the Lord and Lady! (Puts pentacle on.)
Now my dedication is complete, and the paths are many and varied before me. May I go and grow with happiness and the power of the love of the Gods.
