Having a godly mother is THAT important - even for God: "And Mary said, 'My soul magnifies the Lord, and my spirit rejoices in God my Savior, for He has looked on the humble estate of His servant...'" Luke 1:46-55.
“One can’t help but wonder their thoughts as they looked into each other’s eyes, or about their interactions as Jesus grew from baby to toddler, toddler to little boy and from boy to man. What did Mary teach Jesus and what did He teach her? No doubt their relationship was one of devotion and unity as they obediently fulfilled the Father’s will throughout their lives.” Art by Jean Keaton
"as Mary is the treasurer and dispenser of the gifts and graces of the Most High God, she reserves a choice portion, indeed the choicest portion, to nourish and sustain her children and servants. they grow strong on the Bread of Life; they are made joyful with the Wine that brings forth virgins. they are carried at her breast. they bear with ease the yoke of Christ scarcely feeling its weight because of the oil of devotion with which she has softened its wood." — st. louis de montfort
