This is a short but
lovely and meaningful Coven ritual that I found from Kate West's book
The Real Witches' Coven.
Choose two men, preferably equally
matched, who can take the roles of the Oak and Holly Kings. Make sure to
give them plenty of advanced warning so they have time to practice their
battle.
"Welcome.
This is Litha, the Summer Solstice, the longest day and the height of
the Sun's power. But herein lies the paradox. For even as the Sun
reaches the height of its power, it begins to decline." "At
this time, Lord Holly once more challenges His brother the Oak King, and
wins. For now he will preside over the darkening half of the year." "This
is also the time of the trickster Gods, the time of Pan, Puck and Loki,
and of the Goddesses and Gods of humor and jest. And in keeping with
this we celebrate with mirth and joy, as well as with reverence. Blessed
Be.." After the explanation, the High Priestess should crown first the Oak
King, saying: "This
is the Oak King who reigns over the waxing Sun." It
is important that the crown is secure on the King's head.The
Priestess turns to the rest of the group and says: "All
Hail the Oak King!" All
(repeat 3 times): "All
Hail the Oak King!" The
uncrowned Holly King steps forward to challenge the Oak King: "Your
time is over, you are old and past your best. It is time to make way for
my youth and strength. For I am your brother, Lord Holly, and my time is
now."
The Oak King
replies: "I
am the Oak King and I will not step down for you my brother. You seek
the crown, then you must first prove yourself, and take it, if you can."
The
two Kings then proceed to battle. The rest of the group should give them
plenty of room, but should also should and cheer them on. Once
Lord Holly has defeated the Oak King, he should remove his crown and
return to the High Priestess who then crowns the Holly King with the
other crown, saying: "To
the victor the crown. This is the Holly King who presides over the
waning Sun. He has challenged and fought bravely and he has won. But let
everyone remember that Lord Oak is still with us and as the Wheel of the
Year surely turns he will once again have his chance."
She
turns to the group and says: "All
Hail to the Holly King!" All
(repeat 3 times): "All
Hail to the Holly King!" The
Holly King and the High Priestess then perform the Rite of Cakes and
Ale, with Lord Oak standing to her left.
