All gods, indeed all creation discovers its oneness in the Divine. After there can be only One Source, One Origin of creation and whatever we find in creation must be somehow connected with and find its origin in the One. The gods too owe their origin in the Divine and are His aspects and powers.
However it is equally true that each god has its own unique function otherwise there would not be any need of different gods.
The greatest of all truths however is that human being himself is a god though he has forgotten it. Yet it is given to man to discover the Divine within him and thereby be as the gods, oneself a power of the Divine for His Work upon the world.
Affectionately,
