100. In what way is the spiritual motherhood of Mary universal?
501-507
511
Mary had only one Son, Jesus, but in him her spiritual motherhood extends to all whom he came to save. Obediently standing at the side of the new Adam, Jesus Christ, the Virgin is the new Eve, the true mother of all the living, who with a mother's love cooperates in their birth and their formation in the order of grace. Virgin and Mother, Mary is the figure of the Church, its most perfect realization.
101. In what sense is the life of Christ a Mystery?
512-521
561-562
The entire life of Christ is a revelation. What was visible in the earthly life of Jesus leads us to the invisible mystery of his divine sonship: “whoever has seen me has seen the Father” (John 14:9). Furthermore, even though salvation comes completely from the cross and the resurrection, the entire life of Christ is a mystery of redemption because everything that Jesus did, said, and suffered had for its aim the salvation of fallen human beings and the restoration of their vocation as children of God.
102. How did God prepare the world for the mystery of Christ?
522-524

God prepared for the coming of his Son over the centuries. He awakened in the hearts of the pagans a dim expectation of this coming and he prepared for it specifically through the Old Testament, culminating with John the Baptist who was the last and greatest of the prophets. We relive this long period of expectancy in the annual liturgical celebration of the season of Advent.
