Jesus, Mary and Joseph form the “HOLY” family.
Holy means different. Jesus is true God and true man. Mary is full of grace – sinless. And Joseph is reputed to be a just man.
Persons are subjects of rights and duties. Jesus, must be about his Father’s business. But he was obedient to Mary and Joseph. Mary and Joseph cared for Jesus. So “Jesus advanced in wisdom and age and favor before God and man.” (Lk. 2: 52)
