In the Norse/Germanic cosmology, Frey is a member of the second pantheon of Northern Gods, the Vanir Gods of Vanaheim, who are all concerned with agriculture and food-gathering of some sort. He is the son of Nerthus the Vanir Earth Mother, and Njord the god of sailors and fishermen. His twin sister is Freya, the goddess of fertility and love. His beloved wife is Gerda.
Frey is the Golden One, the Sacrificial Grain God, the one who is cut down at every harvest that we may live. He is the keeper of every plant and animal who is killed that we might live. He is a god of frith - peace and order - as opposed to being a god of war and conflict. He is a Lover, the great Maypole in the Earth. He is a Light-Bringer, a Joy-Bringer, a Frith-Bringer, a Gift-Giver, the Harvest King, John Barleycorn. He asks that we think about the food that we eat, how it was raised and treated, and whether it died in a clean manner. He asks that we think about how we treat those we love.
His gifts are many. He gives fertility of body and fertility of land. He blesses the farmer and his crops and livestock. He bestows sexual desire and potency. He bestows love in all forms, regardless of what combination of people and genders may be involved. He blesses ephemeral sexual joy that is shared for a night, and he also blesses committed marriage - especially relationships that are frowned upon by the greater social order. He gives the light within that stands against the darkness of sorrow. As the God who gave up his sword for love, he helps foster peace in social affairs. He helps those who must sacrifice for others find joy and contentment in their giving.
Enjoy the love of Frey.
