I think there a few points that needed to be added to this discussion. First is that the Jeremiah verses are out of context--they concern by my understanding the Assyro-Babylonian Ishtar, a goddess of fertility, that followers offered cakes shaped like stars to.
Next, Catholism 101 for those who are not aware. We do not treat Mary as God or adore Mary, that is only reserved for God alone. We do however, ask Mary to intercede for us. This does not contradict our belief that there is only one mediator between God and man, our Lord Jesus Christ. Everything goes through Mary to Jesus and anything we receive from Mary comes from Jesus. If I ask you to pray for me will you refuse on the basis that their is only one mediator between God and man--and you are not it? And if your prayers for me are answered, does that mean it came from you--or Jesus? I have problems understanding why someone experiencing everlasting life and in union with the Holy Trinity would be so much different from someone on Earth in their ability and desire to pray for us. James 5:16 tells us that the prayers of righteous person availth much, is there anymore righteous than those united with Jesus in Heaven?
Let us also consider other Bible with reference to Mary: Should we not pray as the Psalms as the KJV puts it "Precious in the sight of the Lord is the death of his saints. O Lord, truly I am thy servant; and the son of thine handmaid; thou hast loosed my bonds."(Ps 116:15-16).
In John 19 we see John is not referred to as John, but the beloved disciple, and Jesus gives his mother to him, and him to His mother. In Rev 12 we need to look also at this woman who gave birth to Christ, and in verse 17 we find that she is the mother of others that the devil wages war against who keep the commandments and bear testimony to Jesus. She is also our mother. In Rev 12:1-2 we see that in Heaven she is present with a crown of 12 stars, and clothed in the sun with the moon at her feet. Is that promised to us also, or is this a special honor God bestows on Mary? Would Jesus not honor His mother and father? Should we degrade our spiritual mother and talk evil about her? What does it say for us if Mary who God said through the angel Gabriel is "highly favored" (Lk1:28, KJV),and whom God has done great things for (Lk 1:49) can carry Jesus physically inside of her and physically live with Him all those years and love him only as a mother can love a child, and still be a reched person--what chance do we have? It doesn't make sense to me. Should we really work on trying to rid out what the Bible says through Mary's canticle that "all generations will call me blessed" (Lk 1:48).
Also, let us not forget the detail that God had in building the Ark of the Convenant, the dwelling place of God among his people. Why would God put so much detail in that Ark, but for Mary not want the same detail for his dwelling place for 9 months? And does Lk 6:43-44 have some special exemption to Mary? If the "tree is know by it's fruit" then shouldn't Mary be know for the tree she was born as, as the mother of Jesus? Should we not love Mary for nothing more than the way she loved Jesus prior to His horrible Passion.
Regardless of your faith, I believe everyone who strives to live a Christian life can see the wisdom in an old saying of the Catholic Church, which is: Love Jesus as Mary loved Jesus, and love Mary as Jesus loved Mary.
