Mary Daly is a theologian and philosopher of the 20th century who, in the latest evolution of his thought, has radically considered Christian theology and the systems based on it as limiting women and legitimizing the authority of men. He believes that this theology has acted hierarchically in its doctrines, symbols, and institution, i.e. the church, and by turning women into others, it has denied and distorted them and their experiences and knowledge. God the Father, Christ, the descent, the church, and male-oriented ethics are the things that Daly goes through as the foundations of sexism in theology. He considers God as a verb and calls it "being" and instead of the idea of a male incarnation of God, he says "second appearance", i.e. the dynamic intuition of existence as the way of God's communication with creatures, and "descend" instead of exiting from the sublime to mean entering that. From her point of view, the new space is a sister cosmos that is realized through "becoming a woman". Becoming a woman is the realization of women's existence through participation with existence, and it has two sides of individuality and participation. The collective aspect of becoming a woman or sisterhood is due to the inclusion of the circle, as a result of which, finite beings actively participate in something that they all share in, and this causes the realization of cosmic ontological collective participation. The women's revolution is not exclusive to women; Because it seeks bisexuality of man and crossing gender dualities, but these are the women who started it with the intuition of existence, they receive this insight in a way that they spread it to others. Since the Since women have always been outsiders of the theological system, they have different conditions compared to men who have not been subjected to this oppression, and therefore, "equality" is not a sufficient solution for the journey towards bisexuality. The most frequent word in Daly literature is "freedom". In his opinion, freedom is not just a political, sexual, or social thing. He proposes freedom as the meaning of becoming a human being and participation in existence, and it is related to the goal and happiness. Therefore, in his view, freedom is a philosophical and theological issue.
