Catholic Mariology is Mariology (the systematic study of the person of Mary, mother of Jesus, and of her place in the Economy of Salvation) in Catholic theology. According to the Immaculate Conception taught by the Catholic Church, she was conceived and born without sin, hence Mary is seen as having a singular dignity above the saints, receiving a higher level of veneration than all angelic spirits and blessed souls in heaven. Catholic Mariology thus studies not only her life but also the veneration of her in daily life, prayer, hymns, art, music, and architecture in modern and ancient Christianity throughout the ages. The four Marian dogmas of Mother of God, Immaculate Conception, perpetual virginity, and Assumption form the basis of Mariology. However, a number of other Catholic doctrines about the Virgin Mary have been developed by reference to sacred scripture, theological reasoning and church tradition. The development of Mariology is ongoing and since the beginnings it has continued to be shaped by theological analyses, writings of saints, and papal statements, e.g. while two of the dogmas are ancient, the other two were defined in the 19th and 20th centuries; and papal teachings on Mary have continued to appear in recent times. In parallel to the traditional views, since the late 19th century, as Marian devotion became more pronounced in the Catholic Church, a number of other perspectives have been presented as a challenge to Catholic Mariology. Other Christian views see Catholic Mariology as unbiblical and a denial of the uniqueness of Christ as redeemer and mediator, and modern psychological interpretations see Mary as the equivalent of mythical goddesses ranging from Diana to Guan Yin. Nonetheless, most Christians including the Latin Church led by the pope, the Eastern Orthodox Church, the Oriental Orthodox Church, and the Church of the East revere Mary as the greatest saint and disregard Protestant objections to Marian devotion. Study of Mary and her place in the Catholic Church Context and components The study of Mary and her place in the Catholic Church has been undertaken from a number of perspectives and within a number of contexts, and in his address to the 2012 Mariological congress, Pope Benedict XVI stated that this study must be "understood and deeply examined from different and complementary viewpoints". Benedict also emphasized that the study of Mary cannot be performed in isolation from other disciplines and that Mariology is inherently related to
