In the Communion of Saints, which is the true Church Universal and Catholic, the mystery of the New Humanity is disclosed as a new existential situation. And in this perspective and living context of the Mystical Body of Christ the person of the Blessed Virgin Mother appears in full light and full glory.
The Church now contemplates her in the state of perfection. She is now seen as inseparably united with her Son, who “sitteth on the right hand of God the Father Almighty.” For her the final consummation of life has already come—in an anticipation. “Thou art passed over into Life, who art the Mother of Life,” acknowledges the Church, “Neither grave nor death had power over the Mother of God . . . for the Mother of Life hath been brought into Life by him who dwelt in her ever-virgin womb” (Troparion and Kontakion for the feast of the Assumption of the Virgin Mary, Koimesis).
Again, it is not so much a heavenly reward for her purity and virtue, as an “implication” of her sublime office, of her being the Mother of God, the Theotokos. The Church Triumphant is above all the worshipping Church, her existence is a living participation in Christ’s office of intercession and his redeeming love. Incorporation into Christ, which is the essence of the Church and of the whole Christian existence, is first of all an incorporation into his sacrificial love for mankind.
And here there is a special place for her who is united with the Redeemer in the unique intimacy of motherly affection and devotion. The Mother of God is truly the common mother of all living, of the whole Christian race, born or reborn in the Spirit and truth. An affectionate identification with the child, which is the spiritual essence of motherhood, is here consummated in its ultimate perfection.
The Church does not dogmatize much about these mysteries of her own existence. For the mystery of Mary is precisely the mystery of the Church. Mater Ecclesia and Virgo Mater, both are birthgivers of the New Life. And both are orantes. The Church invites the faithful and helps them to grow spiritually into these mysteries of faith which are as well the mysteries of their own existence and spiritual destiny. In the Church they learn to contemplate and to adore the living Christ together with the whole assembly and Church of the firstborn, which are written in heaven (cf. Heb. xii. 23).
And in this glorious assembly they discern the eminent person of the Virgin Mother of the Lord and Redeemer, full of grace and love, of charity and compassion—”More honorable than the cherubim, more glorious than the seraphim, who without spot didst bear the Eternal Word.”
In the light of this contemplation and in the spirit of faith the theologian must fulfill his office of interpreting to believers and to those who seek the truth the overwhelming mystery of the Incarnation. This mystery is still symbolized, as it was in the age of the Fathers, by a single and glorious name: Mary— Theotokos, the Mother of God Incarnate.
