This article, meeting the lively interest in the issues of virginity and motherhood of Mary in contemporary Mariology, tries to show these two important truths in the teaching of St. Augustine based on his sermones for Christmas. The Marian title Virgo Mater was chosen as the most representative for the issues at hand and it is the guide in considerations which, apart from the introduction and conclusion, include the following issues: Sermones de Natali Domini, Nativitas Christi duplex, Maria Virgo Mater, Virginalis maternitas Mariae and Maria Mater et Virgo et Ecclesia mater et virgo. The basic method of work is the salvation history method, with a clear use of the tools of the hermeneutics of language, image and symbol, as well as the mystagogy characteristic of Mary. Careful reading of the Marian message of the great Father and Orator of Christian antiquity leads to the conclusion that so important in the mystery of the Incarnation -Mary's virginity and motherhood are not only "instruments of salvation", but also unique and individual elements of Mary's personality. As the Virgin Mother offered herself to the Divine Son in the first place, so now she offers herself to the Church, to all Christians (omnes Christiani) and to all humanity. The sermons for Christmas by Bishop Hippo in no way measure up to his memorable works, but it cannot be ignored that with their message expressed in a characteristic form and style, for centuries they nourished the piety of many generations of Christians, especially in late Christian antiquity and the early Middle Ages.
