Early landmark publications of a systematic feminist theology include Rosemary Radford Ruether, Sexism and God-Talk: Toward a Feminist Theology (Boston: Beacon Press, 1983). and Elizabeth Schüssler Fiorenza, In Memory of Her: A Feminist Theological Reconstruction of Christian Origins (New York: Crossroad, 1984). A much older textual source would be The Women’s Bible dating back to 1895. For additional references see Fiorenza, In Memory of Her, especially Ch. 1.
