Im going for a culture which endorses and emphasizes gender roles in society. Men and women are equal, but in the complementary rather than egalitarian sense. Magic is only accessible by women. Like the myth will state, it is powerful, but slow, time consuming, and intensive. It may also require multiple ingredients or steps to work. This. along with the history and circumstances of the world, has led to a religious hierarchy where women hold the dominant positions of power.
God, known as the divine, possess a duel nature, each representing different aspects of humanity. The higher half represents the feminine, and symbolizes intuition, wisdom, strength, and life. The lower half, masculine, represents honor, courage, bravery, brawn, and death. These aspects are made manifest in the differences between men and women, and the social order depends on cooperation between the two. By working together, harmony and balance can be achieved. However, division between them causes chaos and strife.
God designed humans for different purposes in mind. He created woman first, and gave her dominion over all creation. The ability to access magic was given to her as proof of her divine authority. This magic was slow, complex, and intensive. However, it was very powerful, able to split oceans in half, rain down fire from the sky, or design new species of plants and animals. With patience, she was able to master it and bend reality to her whim. God then created man, and designated him with the role of defender of creation. He would be a companion to woman, to serve and protect her, and provide council. He was given the gift of physical prowess, which was quicker to access and use, and allowed him to act quickly and desicively when needed. For a time, things were peaceful, and humanity flourished in this golden age. However, although man was strong and quick witted, he was also impatient and overconfident. This made him rebellious, and he grew to disdain woman. Eventually, he sought to subvert her authority over him, and overthrew her with brute force. This is represented in the religion as God's lower half rebelling and subjugation it's higher half. This betrayal ushered in an age of kings, which introduced chaos and strife into the world.
In this new age, man competed and made war with each other, each seeking to dominate their rivals and rule undisputed over creation. The constant wars disturbed the veil that separated reality from the netherworld, where creatures hostile to humanity dwelled. In time, a breach in reality opened in the veil, allowing these demons to pass from their realm into reality. Millions died in the genocide as the demons sought extermination of the human race. Woman, using her intuition and magic, was eventually able to seal the breach and ending the flood of demons into the world. She then created weaponry specifically made to kill the demons, which man used to defeat them. Although humanity was eventually victorious, the world was permanently scarred. The veil was irrevocably damaged, remaining weakened in certain areas or had completely collapsed in others. This allows demons to cross over into reality, and they remain a constant threat to humanity.
With the end of the war, woman was able to reclaim her authority over creation. In her infinite love and wisdom, she forgave man for his betrayal, knowing that God's halves cannot exist without the other. However, men was punished for their arrogance by bearing the responsibility for causing the calamity that almost ended the human race. They must carry that shame throughout their lives making penance until god redeems them in the hereafter. The story is meant to be an inverse of the creation story in the bible, and used by the matriarchy to "justify" it's rule. Like Eve, who caused humanity to get kicked out of the garden of eden and the introduction of original sin, it was man who led to the end of humanity's golden age and introduced chaos into the world. Keep in mind while it embraces equality of the sexes, it's obviously skewed in benefiting one gender over the other, which is the point.
Taking human psychology and socialogy into account, Would this be a reasonable creation myth that a matriarchy could use to justify its authority? How can I make it sound more authentic?
