Mariology is the theological study of Mary, the mother of Jesus. Mariology methodically presents teachings about her to other parts of the faith, such as teachings about Jesus, redemption and grace. Christian Mariology aims to connect scripture, tradition and the teachings of the Church on Mary. In the context of social history, Mariology may be broadly defined as the study of devotion to and thinking about Mary throughout the history of Christianity.
There exist a variety of Christian views on Mary ranging from the focus on Veneration of Mary in Roman Catholicism in Roman Catholic Mariology to Protestant objections, with Anglican Marian theology in between. As a field of theology, in recent centuries the most substantial developments in Mariology (and the founding of specific centers devoted to its study) have taken place within Roman Catholic Mariology. Eastern Orthodox concepts of Mary have been mostly expressed in liturgy and are not subject to a central dogmatic teaching office.
A significant number of Marian publications were written in the 20th century, with theologists Raimondo Spiazzi and Gabriel Roschini achieving 2500 and 900 publications respectively. In terms of popular following, membership in Roman Catholic Marian Movements and Societies has grown significantly. Ecumenical differences continue to exist in substance and style but are more easily understood because of the existence of Mariology. The Pontifical Academy of Mary and the Pontifical Theological Faculty Marianum are key Mariological centers.
