Mary Magdalene played a significant role in the development of Christianity by supporting Jesus during his ministry, being the first witness to his resurrection, and spreading the news of his resurrection. She had a major impact by causing divisions in the church over interpretations of her role, inspiring feminist theology that critiques patriarchal views of women's roles, and serving as a role model for women's leadership and repentance. Her story has led to renewed study of early Christian texts and sparked ongoing debates around power structures in the church.
