She is the "Mother Of
GOD", as shown in Holy Scripture, and by reasoning. She is the
Mother of Jesus Christ.
Matthew 16:18, "And I say to thee, thou art Peter, and Upon
this rock I will build MY CHURCH, and the Gates of Hell shall not
prevail against it."
Ephesians 1:22-23, "And all things He made subject under His feet,
and Him He gave as head over all the Church,
which indeed is His Body, the completion of
Him who fills all with all."
Colossians 1:18, "Again, He is the Head
of His Body, the Church..."
Romans 12:5, "So we, the many, are one
body in Christ, but severally members one of another."
Elucidation...
Jesus Christ founded a Church of which He is the Head and His Body is all
of us.
As a mother, she bore Jesus Christ, just as in Baptism we are born into
the Church, John 3:3-7.
As a mother, she fed Him, just as in the Church we are spiritually fed
by the Sacraments.
John 19:26, "When Jesus, therefore, saw His Mother and the disciple
standing by, whom He loved, He said to His Mother, "Woman, behold,
thy Son." Then He said to the disciple, "Behold, thy Mother".
And from that hour the disciple took her into
his home."
Elucidation...
We all know the disciple Jesus referred to as, "whom He loved",
was the Apostle John. Why didn't John use his name here when he wrote his
Gospel instead of the wording that he did use? It is because "the
disciple whom Jesus loved" is all of us. We are all His disciples,
and He loves all of us. It becomes obvious if you reverse it and say, "Then
He did not love His other disciples, only John, or was John the only disciple
He loved?"
Since the Son IS the Church, along with the rest of us, then His Mother
is rightfully,
the Mother of the Church.
