Outer Manifestations of the God in the Craft
The Wiccan God is the Lord of the Greenwood, consort to the Lady of the Greenwood. Known also as Cernunnos, the Green Man, Herne the Hunter, and Lord of the Wild Hunt, he is a god of fertility, growth, death, and rebirth.
Two God-themes figure predominantly in Wiccan Sabbats: the Sun-God theme and that of the Holly King and Oak King.
The Sun-God rules the seasons. At Yule, he is the new babe, the embodiment of innocence and joy. He represents the infancy of the returning light. At Imolg, his growth is celebrated, as the days are growing longer and light stronger. At Ostara, he is a green, flourishing youth whose eye is taken by the Maiden Goddess. On Beltane, he is the young man in love who takes the Goddess as his bride. Their consummated marriage is celebrated with maypoles and bonfires. At Midsummer, he consumates his marriage in a union so complete that it becomes a death. He is mourned at Lammas, and at Mabon, he sleeps in the womb of the Goddess. At Samhain, he waits in the Shining Land to be reborn.
The symbolism of the Horned God is also played out in the theme of the Holly King and Oak King. The Horned God is the Holly King and the Oak King, two twin gods seen as one complete entity. Each of the twin gods rule for half of a year, fights for the favor of the Goddess, and dies. But the defeated twin is not truly dead, he merely withdraws for six months, some say to Caer Arianrhod, the Castle of the ever-turning Silver Wheel, which is also known as the Wheel of the Stars. This is the enchanted realm of the Goddess Arianrhod where the god must wait and learn before being born again. Arianrhod means "silver wheel" and the castle is the Aurora Borealis. She is the goddess of the astral skies and there she rules as goddess of reincarnation. The golden Oak King, who is the light twin, rules from midwinter to midsummer. The darksome Holly King rules the dark half of the year from Midsummer to Midwinter.
From the Celtic tradition, we get a pair of ancient pagan images who fight for supremacy at Yule. The Holly King and the Oak King are probably constructs of the Druids to whom these two trees were highly sacred. The Oak King kills the Holly King at Yule. The Oak King then reigns until Midsummer when the two battle again, this time with the Holly King as the victor. The Holly King, who has evolved into the present day Santa Claus, wears red, dons a sprig of holly in his hat, and drives a team of eight deer, (total number of solar sabbats), an animal sacred to the Celtic Gods. Holly and mistletoe are traditional to the season through commemoration of the battle. The holly was hung in honor of the Holly King; the mistletoe in honor of the Oak King.
The Oak King and Holly King are mortal enemies at Midsummer and Yule, but they are two sides of a whole, and neither could exist without the other.
