He was submissive to his mother. “He went down with them and came to Nazareth and was submissive to them [his parents].” (Luke 2:51)
He spoke with courtesy to his mother. As of John 2:1-5 Jesus is already living out of the house, already about thirty years old, already anointed with the Spirit, and already acting with authority. His mother says, “They have no wine!” Jesus replies, “Woman, what does this have to do with me? My hour has not yet come.” But she evidently knew he’d do it anyway: “His mother said to the servants, ‘Do whatever he tells you.'”
Notice how Jesus calls her “woman”. Jesus is not under her authority, but he does address her with courtesy and respect. BDAG: “The voc. (ὦ) γύναι is by no means a disrespectful form of address.” EDNT: “Voc. γύναι is not irreverent in Matt 15:28; Luke 22:57; John 2:4; 4:21; 19:26; 20:13, 15.” Liddel-Scott: “in voc. often as a term of respect.”
Jesus ensured that a trusted disciple would take care of his mother. “When Jesus saw his mother and the disciple whom he loved [John] standing nearby, he said to his mother, “Woman, behold, your son!”” (John 19:26)
Jesus died for Mary. Jesus told his disciples, “Greater love has no one than this, that someone lay down his life for his friends.” Paul wrote, “Christ loved the church and gave himself up for her.” And, “God shows his love for us in that while we were still sinners, Christ died for us.”
This includes his mother. Mary was a sinner, a friend of Jesus, and a member of the Bride of Christ. She rejoices with the rest of us believers:
“For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life. More than that, we also rejoice in God through our Lord Jesus Christ, through whom we have now received reconciliation.” (Romans 5:10-11)
