What was Jesus’s relationship to Mary?
Well, the obvious answer is that Mary was the Mother of the Human form of Jesus. But was Jesus the Human Son of Mary just as any human has a mother? Jesus is God, so is it reasonable to accept the fact that Jesus, Son of God, is subject to His mother as any son is to his mother and father? Yes.
Jesus reiterated the teaching and 4th Commandment that a son or daughter is subject to their parents and must respect them.
If the Son of God gives respect to Mary because Mary is His Mother, what does that tell you about how to treat your parents?
