Sorcery and Kanaloa as the Devil

Sorcery In Ancient Hawaii, sorcery was one of the strongest forces in shaping the life and character of the Hawaiian people. Sorcery also was one of the determining factors in the careers of her leaders.
Sorcery was commonly practiced through the use of fetchers made in the shape of an image called ki'i (tiki?). This ki'i was believed to be possessed by the spirit of a powerful ancestor or a nature spirit, who was worshiped for the purpose of bringing the mana (power) of the god under control of its keeper. The bones of a dead family member was also preserved and worshiped in the same manner, called unihipili. A corpse was also dedicated to some powerful god. The body woud then be changed into that of some form, recognizable to the family by some mark on its body, and into this body the spirit of the dead would enter. If it was worshiped by the family, it would take that family under its protection, punish their enemies, and bring the family good fortune. Such a protector was called an aumakua.
Such a god was valuable to a family, but it had its dangers as well. If its worship was neglected or its kapu forgotten, the aumakua visited vengence upon its own family. Because of the strong sense of family descent, every such god became a link in the chain which bound each succeeding generation to the kapu imposed by their ancestral guardian. On the other hand, the mana from theses ancestral gods became the right of every member of the family should he at any time seek help from such a guardian. However, if such a god proved ineffective, it might be disregarded for a stronger.
Spirits might also possess a living person and convey messages in this way. These spirits were called akua noho (sitting god), and the person the god entered was regarded as a god during the time of possession. The person that the god entered did not have any power, only the spirit which possessed him had power. Sorcery began when these possessing spirits were sent abroad to do injury to another.
Dealings in sorcery were not confined to the chiefs and priests but spread among the people. Not everyone who kept an aumakua made use of it for sorcery. However, such persons were feared by their neighbors. The chiefs tried to put an end to sorcery and made laws against it. Counter-
practioners arose who fought sorcery with sorcery, and the practice only increased.
There were many gods and goddesses who were worshiped as Sorcery gods:
Uli - is the principal deity worshiped by sorcerers. She takes presedence over Haumea
Pahulu - goddess from Molokai. The Island of Molokai is said to be the center of the 'strongest'sorcery in the whole group.
Pele - the fire goddess. All the Pele deities are associated with sorcery.
Kapo - is worshiped as an akua noho. One of the daughters of the sorceress Haumea.
Pua - also worshiped as an akua noho.
Ku War Gods - all the images of war gods namedunder Ku are sorcery gods.
Kuho'one'enu'u - worshiped on Oahu by chiefs as a war god.
Kukeoloewa - war god worshiped on Maui and Molokai
Maka-ku-koae and Alae-a-Hina - invoked together with Uli by sorcerers for the purpose of bringing death to an enemy. Maka-ku-koae is the
 god who brings madness (pupule), insanity (hehena), or imbecility (lolo). Alae-a-Hina is the sorceress from whom Maui wrested the secret
 of fire.Kamaunu - sorceress grandmother of the hog-man Kamapua'a
Some confusion as to the sex of the dual characters of these gods/goddesses of sorcery can be explained by the fact that the male sorcerers seem to work through a female companion as akua noho.
The origins of the orders of sorcery have many elements in common. One of these common elements is observed in the make-up of the group who initiate the order. They seem to appear in groups of three consisting of one woman and two men. Haunea (goddess of the earth, and mother of Pele) come to Hawaii with Kane (the supreme god) and Kanaloa (the Hawaiian Lucifer); Pele is accompanied by her two brothers, Moho (Ka-moho-ali'i) and Kamakaua (Ke-o-ahi-kamakaua); and Kamunu (grandmother of Kamapua'a) comes to Maui with two men both of whom claim to be her husband (at different times). Uli is also associated with two brothers.
