Here’s what Jesus had to say about his mother and his brethren and if any were held higher than the other in Matthew 12:
47Then one said unto him, Behold, thy mother and thy brethren stand without, desiring to speak with thee.
48But he answered and said unto him that told him, Who is my mother? and who are my brethren?
49And he stretched forth his hand toward his disciples, and said, Behold my mother and my brethren!
50For whosoever shall do the will of my Father which is in heaven, the same is my brother, and sister, and mother.
He says that whoever does the will of God His Father that they are all the same, his brother in God, sister in God, or mother. Mary is said to be the same as anyone else according to Jesus.
And here is what Jesus said when a woman tried to exalt Mary in 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.
28But he said, Yea rather, blessed are they that hear the word of God, and keep it.
He didn’t agree with the woman. He said “rather, blessed is the person that hears God’s word and keeps it.” He never said, “yes, she is blessed.” He said, “no, blessed is someone who hears my father’s words and keeps them.” Everyone is equal to Mary, Jesus said so himself.
