Mary continues to be a source of theological interest and concern for Catholics and Protestants alike. For Catholics, Mariology was codified in a set of dogmas over the centuries; yet many Catholics remain unaware of the biblical, historical, and theological matrix that gave rise to the magisterial teaching. Protestants, with some exceptions, remain skeptical of Marianism in Catholic theology, viewing such as intrusions upon biblical doctrine and faith or unnecessary accretions threatening of sound Christian theology. Aidan Nichols, OP, attempts to address this "puzzlement" of Mary. Working through the biblical, patristic, and medieval sources, Nichols introduces readers to the robust scriptural and theological bases for the Church's celebration of Mary in its doctrine and liturgy, alongside the work of the Councils and the magisterium, to argue for the crucial relevance of Mary in the theological articulation of the gospel, the celebration and practice of the liturgy, and the sacramental life of the Church. The present study aims to contribute to the revival of a more full-blooded Marian teaching and attempts to take the path set by ressourcement theology in recovering the robust voice of witness to Mary.
