An Earth Centered or Pagan ceremony is fairly easy to organize. Couples can choose readings and vows and work with the celebrant on how to conduct the ceremony. Some couples will invoke the blessing of the God and Goddess, which are acknowledged to come in thousands of forms. The couple light a candle to honor the gods and signify the beginning of their new life. The couple may further invoke the blessings of the spirits by saying 'blessed be'. The celebrant will then conduct the handfasting ritual, asking the couple to join hands and wrapping the joined hands in a strip of red cloth. Gay couples may choose to have a rainbow hand fasting, using gay accessories of strips of red, orange, yellow, green, blue and purple cloth to represent the chakras and their sexuality. The couple then exchange vows, asking the sky and earth to bestow the union with their elements.
Couples who are interested in traditional paganism may choose to include a broom, to sweep away past hurts, and a chalice of wine, to represent their combined spirits. The expression Tie The Knot comes from the Handfasting Ceremony where a cord, usually red, was tied around the couple's hands.
Some couples have found these books helpful. Most are available from your local library or bookstore.
