Paragraph Number	Main Topic	Key Thought
LG 48	The eschatological character of the Church; renewal of the world in Christ	The Church will reach its fullness in heavenly glory.

VIII: The Blessed Virgin Mary, Mother of God in the Mystery of Christ and the Church

Paragraph Number	Main Topic	Key Thought
LG 52	Introduction: Mary in the mystery of salvation and the Church	God willed to save the world through the Incarnation. Mary as Mother of God and Mother of the Redeemer holds the first place in the Church’s veneration after Christ.
LG 53	The dignity and role of Mary in the economy of salvation	Mary—Mother of God and of the Redeemer, redeemed in a more exalted way, endowed with the highest dignity. United with all people through descent from Adam; mother of the members of Christ and model of faith and charity.
LG 54	The scope of the Council’s teaching on Mary	The Council explains Mary’s role in the mystery of the Incarnate Word and the Church, but does not intend to present a complete Mariology. Theologians remain free in their reflections on the One who holds the highest place after Christ.
LG 55	Mary in the Old and New Testament; preparation of the economy of salvation	Old Testament prophecies gradually reveal Mary as the Mother of the Savior. She holds the first place among the humble and poor of the Lord; with her comes the fullness of time and the new economy of salvation.
LG 56	The Immaculate One; the will of the Father and Mary’s cooperation in salvation	The Father willed that the Incarnation be preceded by Mary’s consent. Endowed with special holiness, conceived without the stain of sin, she responds to the Annunciation with complete obedience. Not passively, but actively she cooperates in the work of salvation (parallel: Eve–Mary).
LG 57	The bond of Mary with her Son from conception to death	From virginal conception through birth, to the temple, to the public teaching—Mary accompanied her Son. At the cross she stood without God’s decree having imposed it, she suffered with him, and was given as mother to the disciple.
LG 58	Mary in the public life of Jesus; her attitude of faith	At Cana in Galilee she interceded for those in need. She watched over her Son’s teaching, which places heavenly ties above bonds of blood. She journeyed onward in the pilgrimage of faith until the cross, where she co-offered her Son.
LG 59	Mary after the Resurrection; the Immaculate Conception; the Assumption	On the day of Pentecost she remained with the Apostles in prayer. Immaculate from the first moment of conception, having completed her life on earth, she was taken up into heavenly glory, exalted as Queen.
LG 60	The unique mediation of Christ and the role of Mary	Mary does not dim the mediation of Christ but reveals his power. Her saving influence flows from God’s good pleasure and draws from the merits of Christ; it strengthens (does not hinder) the direct union of the faithful with Christ.
LG 61	Mary—Mother in the order of grace	Mary, destined to be the Mother of God, became in a special way the cooperator of the Savior through faith, hope, and charity. In conceiving, nourishing, offering Christ, and suffering with him at the cross—she became mother to us in the order of grace.
LG 62	The motherhood of Mary in the economy of grace—unceasing	From the Annunciation to eternity: Mary persists in her saving task. In heaven through her manifold intercession she obtains for us the gifts of salvation. She cares for the brothers and sisters of her Son, pilgrims on earth. Titles: Advocate, Helper, Auxiliary, Mediatrix (these diminish nothing from Christ).
LG 63	Mary—the type (pattern) of the Church	Mary, united with her Son the Redeemer through motherhood, is deeply bound to the Church. She is the first exemplar of faith, charity, and perfect union with Christ. She stands first as a model of virginity and also of motherhood.
LG 64	The Church imitates Mary and becomes mother and virgin	The Church, contemplating the mystery of Mary, imitating her charity and fulfilling the will of the Father, itself becomes mother (through preaching and baptism) and virgin (preserving inviolate faith, hope, and charity).
LG 65	Mary—model of virtues for the pilgrim Church	While Mary in the Church already achieves perfection, Christians continually strive to grow in holiness, lifting their eyes to Mary as a model. Contemplating her, the Church penetrates more deeply into the mystery of the Incarnation and conforms itself to Christ.
LG 66	The cult of Mary—special, not identical with the cult of God	Mary, exalted above all after her Son, rightly receives special veneration. Since the Council of Ephesus, a cult expressing itself in honor, love, invocations, and imitation. A unique cult, essentially different from the cult of adoration (offered to Christ).
LG 67	Instruction on the cult of Mary and its proper practice	The Council earnestly recommends supporting the cult of Mary, especially the liturgical, and valuing pious practices. It encourages theologians and preachers: to explain Mary’s gifts without exaggeration or narrowness, always relating them to Christ. True piety flows from faith.
LG 68	Mary—sign of certain hope for the pilgrims	Mary, already enjoying glory in heaven (in body and soul), is the image of the future perfection of the Church. On earth she shines upon the pilgrim People of God as a sign of certain hope and consolation.
LG 69	Call to prayer and unity	All Christians should beseech Mary, Mother of God and of mankind, that she intercede for us within the Communion of Saints. The prayers of Mary sustained the beginning of the Church; may they support all humanity toward peace and unity in one People of God.
