Pope John Paul II
1986 Encyclical
Dominum et Vivificantem
On the Holy Spirit in the Life of the Church and the World

"The Church perseveres in prayer with Mary. This union of the praying Church with the Mother of Christ has been part of the mystery of the Church from the beginning: we see her present in this mystery as she is present in the mystery of her Son. It is the Council that says to us: "The Blessed Virgin...overshadowed by the Holy Spirit... brought forth...the Son..., he whom God placed as the first-born among many brethren (cf. Rom 8:29), namely the faithful. In their birth and development she cooperates with a maternal love"; she is through "his singular graces and offices... intimately united with the Church.... [She] is a model of the Church."(285) "The Church, moreover, contemplating Mary's mysterious sanctity, imitating her charity,... becomes herself a mother" and "herself is a virgin, who keeps...the fidelity she has pledged to her Spouse. Imitating the Mother of The Lord, and by the power of the Holy Spirit, she preserves with virginal purity an integral faith, a firm hope, and a sincere charity."(286)"
