Luke 8:21 And he answered and said unto them, My mother and my brethren are these which hear the word of God, and do it.
Luke 11:27And it came to pass, as he spake these things, a certain woman of the company lifted up her voice, and said unto him, Blessed is the womb that bare thee, and the paps which thou hast sucked. 28 But he said, Nay rather, blessed are they that hear the word of God, and keep it.
Jesus rebuked those who would venerate Mary for the wrong reasons.
Mary heard the word of God and obeyed, that is why she is blessed and if we do the same we are blessed also.
It is what Catholics are constantly telling protestants about Mary, but their hearts are hardened, made of stone.
Mary is what she is because Jesus is who He is.
