Attaining a doctorate in philosophy, with an emphasis on the feminist writings of Simone de Beauvoir, Murray taught philosophy in college. For many years, she launched a personal vendetta against God and the Catholic Church in the classroom, trying to persuade students that God did not exist, mocking values Catholics hold dear, and touted feminism as the cure for many social ills. When she discovered she was pregnant, Murray followed the route that feminists offer as a solution for unmarried women. Much to her surprise, her abortion was a shattering emotional experience, which she grieved over for years. It was the first tragic chink in her feminist armor.
After her marriage in 1982, she anguished over the decision to have children, but became an advocate of the "child-free" movement, believing children were burdens and life could be happy life without them. Later in her forties, Murray experienced a mysterious series of events in which it seemed that "someone" was inviting her back to God. The mysterious calls came from different ports, including nature, books and other people. Gradually, she realized that the One seeking her was Christ, and the place He was calling her to was the Catholic Church. Eventually realizing it was only in the Church that she would find what she was seeking ù the person of Christ and his love and mercy ù Murray returned to the Church, and finally found healing and forgiveness for the abortion.
