Can I have a verse for that? I don't accept things that can't be proven or at least strongly inferred from scriptures.
And in fact, when you made the statement, the verse that popped to mind was Jesus saying John the Baptist was the greatest as far as those born.
Lk 1:28-29
28 And he came to her and said, “Hail, full of grace, the Lord is with you!” 29 But she was greatly troubled at the saying, and considered in her mind what sort of greeting this might be.
Did you ever wonder why Mary was greatly troubled by the angels greeting? It seems looks a pretty innocuous greeting. It is because he called her a one word name kecharitomene. The root meaning is grace or favor. But Greek is an inflected language so there is a lot more packed into that word. The word does not mean you are being graced or favored right now by my visit. It means at some time in the past you were graced and it was complete. This is why we Catholics believe Mary was comceived without the stain of Adam's sin. God was creating a suitable vessel for the Second Person of Blessed Trinity to assume human form. Remember how strict God was in having the Ark of the Covenant built. It contained 3 things. The tablets of the 10 commandments (Word of God), Aaron staff (Priest) and a jar of manna (Bread of Life) . All three things symbolizing Christ. That means Mary was the New Ark of the Covenant. All this was nothing to do with any merit of Mary it was all the grace of God. When she goes to visit Elizabeth, John the Baptist leaps for joy at the sound of Mary's voice. That is reminiscent if King David danced before the Ark.
Anything that Jesus is King of Mary is Queen. At the beginning of the book of Samuel when the people say they want a king like the nations around them God is not pleased but he gives in. In the ancient world kings had many wives so their mothers served as Queen.
read the books of Kings and evertime a new king is introduced his Queen Mother is named second. Queen Mother is a royal office. You cannot fire your mother. She will always be your mother but you can fire her from the royal office as King Asa did.
2 Chron 15:16
16 Even Maacah, his mother, King Asa removed from being queen mother because she had made an abominable image for Asherah. Asa cut down her image, crushed it, and burned it at the brook Kidron.
The Queen Mother acted as an intercessor between the people and the king.
Remember in the Gospel of John and the Wedding Feast of Cana. Mary tells Jesus they have no wine. Jesus tells her it is not his time.
She tells the servants to do as Jesus says. So at the intercession of Mary Jesus changes the divine timetable. Remember Jesus is True God and True Man. He certainly loves her as God but also as a good Jewish son loves his mother.
As for John the Baptist I do not know. I know Paul said all were sinners. He did not make an exception for Jesus, I think we are just supposed to know he was sinless
