A sister.
Look what Jesus had to say to a woman who tried to honor Mary like you suggest. Luke 11: 27 As Jesus was saying these things, a woman in the crowd called out, "Blessed is the mother who gave you birth and nursed you." He replied, "Blessed rather are those who hear the word of God and obey it."
Matthew 12:46-50 While Jesus was still talking to the crowd, his mother and brothers stood outside, wanting to speak to him. 47Someone told him, "Your mother and brothers are standing outside, wanting to speak to you."
48He replied to him, "Who is my mother, and who are my brothers?" 49Pointing to his disciples, he said, "Here are my mother and my brothers. 50For whoever does the will of my Father in heaven is my brother and sister and mother."
Mark 3:31-35 Then Jesus' mother and brothers arrived. Standing outside, they sent someone in to call him. A crowd was sitting around him, and they told him, "Your mother and brothers are outside looking for you." "Who are my mother and my brothers?" he asked. Then he looked at those seated in a circle around him and said, "Here are my mother and my brothers! Whoever does God's will is my brother and sister and mother."
Luke 8:19-21 Now Jesus' mother and brothers came to see him, but they were not able to get near him because of the crowd. Someone told him, "Your mother and brothers are standing outside, wanting to see you." He replied, "My mother and brothers are those who hear God's word and put it into practice."
Interesting, This event was recorded in three of the four Gospels. I think someone was trying to make a point. Jesus always downplayed the role His mother had to that of any other ordinary person.
His honoring her as His mother here on earth while He was under her authority as a child, does not mean that we are to honor her in the way that the Catholic church demands and teaches, nor does it justify it.
And Jesus doesn't love her more than us. He can't.
Which is precisely, and exactly, what we honor in Mary.
And Jesus doesn't love her more than us. He can't.
He's God. He can do whatever he wants.
