From The Pagan Family by Ceisiwr Serith.
Set the table with your best dishes. Prepare the food for the meal, but do not cook it yet.
Among the food include a loaf of bread in the shape of a Brighid's Cross. Use your favorite bread recipe for this. After the last rising, divide the dough in fourths. Shape each piece into a long roll and fold in half. Hook the piece together to make a simple Brighid's coss and squeeze the tips together. You can bake it the day before or later in the ritual with the rest of the food.
When everything is ready, a woman or girl from the family goes outside with the cross and a lit candle. Alternatively, use a small oil lamp which you can keep next to the stove the rest of the year. She knocks on the door and says:
"Brighid is here, to bless this house.
Open the door, and let her enter."
She does this three times. After the third time, those inside open the door and say:
"Brighid, Brighid,
Come in, come in:
Welcome to our house.
A thousand times welcome."
Brighid comes in and holds up the candle and cross. The other say:
"Lady of Fire,
Burn in our hearts.
Bring the Spring."
She then passes the cross over the flame, saying:
"May the blessing of Brighid be on this cross
and on the place where it hangs
and on all who see it
through all the year."
If the weather is too cold, instead of having a person outside, just put the cross outside, near the door. Put the candle or lamp next to it. When everyone is ready, welcome Brighid and open the door. Bring in the cross and candle and light the candle with the words beginning "Lady of Fire." Then continue with the ritual as written. This may also be done if there is no woman or girl to be Brighid.
One person takes the candle and another the cross and everyone goes to every room in the house. A child can carry the cross. If you have more than one child, they can take turns, changing when you go from one room to another. In each room the cross and candle are held up while someone says:
"Brighid, Lady of Fire,
Watch over this room."
Mark Brighid's crosses with charcoal on your water heater, furnace, and fireplaces or woodstoves as you come to them.
You may wish to bring incense with you as well. Pine is an appropriate incense for Brighid, as it burns fast and hot. The needles of your Yule tree, if you use a cut one, are perfect.
Go to your kitcchen last. If you have a gas stove, blow out the pilot light. Relight it with the flame of the candle (using something as an intermediary) while saying:
"It is Brighid's fire that cooks our food."
(If you relit your pilot light at Yule, do not do so now.)
Then hang the cross over the stove, saying:
"Brighid, Queen of the Hearth,
Keep us safe,
Keep us warm,
Extend your blessing over this our home."
After the cross is hung turn on the stove to start cooking your food. Put the lit candle on the table until after the meal is over. While waiting for the food to cook, spend time doing something as a family.
After dinner the candle is put out by the one who was Brighid at the door (or by the mother or father if you didn't have someone at the door). She says:
"Brighid will shine in our house
through the whole year."
Everyone says:
"Blessings to our Lady Brighid."
Each time you cook or bake, as you turn the oven on say:
"I cook with Brighid's fire."
This is a good reinforcement of her function as hearth guardian. If you use an oil lamp instead of a candle for the ritual, light it when you cook, especially on religious holidays.
