Just the ABSOLUTE necessity to VENERATE her and PRAY to her and ADORE her and LOVE her; right? If you DISHONOR her; she'll get snippy and not LEAD you to her Son.As Catholics, we are not required to pray the rosary; it is a discipline, an aid, a devotional of the faith. And Catholics do not adore [worship] Mary, only Jesus. We do venerate her (regard her with great respect; she's the mother of Jesus, hence God). And love her? Of course! Read 1 Cor 12:31-13:13. And since Mary is without sin, she's not capable of being "snippy." However, much of your commentary is not only snippy, but silly, disjointed, rushed, hence confusing. I'm not always certain where you're coming from in that regard.
No; the reason is that she's DEAD.
