Query: What does Theotokos mean?
Context: Despite Martin Luther's harsh polemics against his Roman Catholic opponents over issues concerning Mary and the saints, theologians appear to agree that Luther adhered to the Marian decrees of the ecumenical councils and dogmas of the church. He held fast to the belief that Mary was a perpetual virgin and the Theotokos or Mother of God. Special attention is given to the assertion that Luther, some three-hundred years before the dogmatization of the Immaculate Conception by Pope Pius IX in 1854, was a firm adherent of that view.
