This paper deals with the problem caused by the traditional attitude of the Catholic Church towards women and their position, in relation to the more open and gender-equal attitude of the Protestant churches. The reason for such an attitude of the Catholic Church is found in its doctrine, which relies on the Bible, emphasizing the dominance of men and the passivity of women. In addition, they see marriage as a union of only a man and a woman, while they strongly condemn everything else. The teaching of the Catholic Church shows the impossibility of its believers living in complete freedom. On the other hand, Protestantism, which consists of a large number of denominations, consists of a number of different positions that they take towards women, and thus there are differences within Protestantism itself. However, looking at Protestantism as a whole, the attitude towards women and their rights is much more liberal than is the case in the Catholic Church. A large part of Protestant churches emphasize the values of freedom and individualism, which play a significant role in defining gender equality. They also accept the so-called a gender ideology that advocates the point of view that it is the man who, through his own upbringing or cultural and social influences, creates a woman and a man. The famous feminist Simone de Beauvoir attracts a lot of attention with the sentence: "One is not born a woman, one becomes a woman." Her statement led to various discussions between the Catholic Church, which strongly condemns the so-called gender ideology and those who support it, fighting for complete gender equality.
