“ Thus there is need of deeper reflection. Before entering into an examination of individual texts, we must direct our attention to the whole picture, the question of structure. Only in this way can a meaningful arrangement of individual elements be obtained. Is there any place at all for something like Mariology in Holy Scripture, in the overall pattern of its faith and prayer? Methodologically, one can approach this question in one of two ways, backwards or forwards, so to speak: either one can read back from the New Testament into the Old or, conversely, feel one’s way slowly from the Old Testament into the New. Ideally both ways should coincide, permeating one another, in order to produce the most exact image possible. If one begins by reading backwards or, more precisely, from the end to the beginning, it becomes obvious that the image of Mary in the New Testament is woven entirely of Old Testament threads. In this reading, two or even three major strands of tradition can be clearly distinguished which were used to express the mystery of Mary. First, the portrait of Mary includes the likeness of the great mothers of the Old Testament: Sarah and especially Hannah, the mother of Samuel. Second, into that portrait is woven the whole theology of daughter Zion, in which, above all, the prophets announced the mystery of election and covenant, the mystery of God’s love for Israel. A third strand can perhaps be identified in the Gospel of John: the figure of Eve, the “woman” par excellence, is borrowed to interpret Mary. ”
