The way Jesus viewed his mother indicates her relative position.
When the wine ran short the mother of Jesus said to him: They have no wine. But Jesus said to her. What have I to do with you, woman?
someone said to him: Happy is the womb that carried you and the breasts that you sucked!
That was a fine opportunity for Jesus to give special honor to his mother and to show that others should do the same.
Instead, Jesus said: No, rather, Happy are those hearing the word of God and keeping it!
Such references show that Jesus took care not to give devotion or undue honor to Mary or to address her by any special title.
He did not allow their relationship to influence him. And the apostles and disciples followed his example, for nowhere in their inspired writings is Mary given any undue honor, title, or influence.
While they respected her as the mother of Jesus, they did not go beyond that.
Certainly they never referred to her as the mother of God.
They knew that Jesus was not Almighty God in human form and, hence, that Mary could not possibly be God’s mother, a position far beyond what God’s Word allows for Mary.
To claim that Mary was the mother of God elevates her to a position where humans would tend to worship her, and that is what has happened for centuries.
