All Marian doctrines must be understood by way of analogy due to her relationship with Christ Jesus.
Christ Jesus is the Prince of Peace. Mary is his mother. The mother of a prince is a queen. Therefore, Mary is the Queen of Peace.
Christ Jesus is the Church. Mary is his mother. Therefore, Mary is the Mother of the Church.
Christ Jesus is God. Mary is his mother. Therefore, Mary is the Mother of God.
Et cetera.
Every single Marian doctrine affirms something about Christ Jesus that is central to the faith.
– Mark L. Chance.
