“But when the time had fully come, God sent forth his Son, born of woman” (Gal. 3:4). This is a scriptural statement of the same mystery with which the Fathers were wrestling at Chalcedon. Now, what is the full meaning and purpose of this phrase: “born of woman?”
Motherhood, in general, is by no means exhausted by the mere fact of a physical procreation. It would be lamentable blindness if we ignored its spiritual aspect. In fact, procreation itself establishes an intimate spiritual relation between the mother and the child. This relation is unique and reciprocal, and its essence is affection or love.
Are we entitled to ignore this implication of the fact that our Lord was “born of the Virgin Mary?” Surely, no docetic reduction is permissible in this case, just as it must be avoided anywhere else in Christology. Jesus was (and is) the Eternal God, and yet Incarnate, and Mary was His Mother in the fullest sense. Otherwise the Incarnation would not have been genuine. But this means precisely that for the Incarnate Lord there is one particular human person to whom he is in a very special relation, — in precise terms, one for whom he is not only the Lord and Saviour, but a Son.
On the other hand, Mary was the true mother of her Child — the truth of her human maternity is of no less relevance and importance than the mystery of her divine motherhood. But the Child was divine. Yet the spiritual implications of her motherhood could not be diminished by the exceptional character of the case, nor could Jesus fail to be truly human in his filial response to the motherly affection of the one of whom he was born. This is not a vain speculation. It would be impertinent indeed to intrude upon the sacred field of this unparalleled intimacy between the Mother and the divine Child. But it would be even more impertinent to ignore the mystery.
In any case, it would have been a very impoverished idea if we regarded the Virgin Mother merely as a physical instrument of our Lord’s taking flesh. Moreover, such a misinterpretation is formally excluded by the explicit teaching of the Church, attested from the earliest date: she was not just a “channel” through which the Heavenly Lord has come, but truly the mother of whom he took his humanity. St. John of Damascus precisely in these very words summarizes the Catholic teaching: he did not come “as through a pipe,” but has assumed of her (ex aftis), a human nature consubstantial to ours (De Fide Orth., 3, 12).
