I do not think anyone can persevere in praying the 15 decade Rosary with humility and devotion, and persist in this error.
One of Our Lady's promises in the recitation of the Rosary is that one will be delivered from heresy.
It is a grace. Heresy is overcome by prayer much more than reasoning. Those who have eyes to see will see, those who do not, will not. The Albigensians were delivered by this holy prayer, more than St. Dominic's preaching.
