What do you mean by "advanced this narrative"--?
How does one "advance a narrative" about Mary?
One just reads Roman Catholic writings on the topic.
Re: Advancing Mary narrative: Where does MARY was conceived SINLESS, Mary was bodily assumed into heaven at her death, Mary is a co-redemtris along with Christ, rosary prayers to Mary, Mary is our mediator, Mary is the Queen of the Universe, Mary is the throat between Christ, the Head and the Body of Christ, the believers, etc.
THIS is how “ONE ADVANCES A NARRATIVE ABOUT MARY”. Traditions and doctrines OF MEN.
