January
1st, Solemnity of Mary the Mother of God
The doctrines of Mary which the
Church believes, teaches, and professes are, in truth, doctrines about Christ.
When the Church says “Mary” she is directing us always to Jesus.
Nowhere is this clearer than in
the central teaching about our Lady – that she is truly the Mother of God. By
insisting that our Lady is not merely the Mother of the Christ, but truly the
Mother of God, the Church condemns two heresies concerning the Savior.
The
Angelic Thomas speaks
“The Blessed Virgin is truly called the Mother of God. For
the only way in which it could be denied that the Blessed Virgin is the Mother
of God would be either if the humanity were first subject to conception and
birth, before this man were the Son of God, as Photinus said; or if the
humanity were not assumed unto unity of the Person or hypostasis of the Word of
God, as Nestorius maintained. But both of these are erroneous. Therefore it is
heretical to deny that the Blessed Virgin is the Mother of God.”

Theologica III, q.35, a.4
