Any simple attempt at describing the belief systems native to the Filipino is likely to be inadequate. The religious beliefs were as varied as the languages of the country.

Among the Kankanai Igorots, the dog was almost worshipped, in a manner similar to other tribes throughout the Malay archipelago; some of whom even gave their dogs amulets to wear against sickness and danger.

However, among some neighboring Igorot tribes, the dog, while considered sacred, is killed and eaten during sacrifices.

Throughout the Philippines, there was a great diversity of belief.

In the Philippines, the record of the Spanish, and the surviving indigenous traditions leave little doubt that the Filipinos had a belief in a Supreme Creator God.

The name of this god varied depending on what region is discussed. Among some of the names are: Bathala, Diwata, Kabunian, Mansilatan, Makaptan, Laon, Lumauig, Mamarsua, Tuhan.

The Creator God was almost always said to be invisible, or without form, and as such, images of the deity were not generally made. The name was considered sacred, and very rarely uttered, usually only in sacred rituals by special initiates.
