. . . She is our Mother in the order of grace
By her complete adherence to the Father's will, to his Son's redemptive work, and to every prompting of the Holy Spirit, the Virgin Mary is the Church's model of faith and charity. Thus she is a "preeminent and . . . Wholly unique member of the Church"; indeed, she is the "exemplary realization" (typus) of the Church.
