With all due respect, I believe Mary was no more righteous than we are and that the elevation of her by Catholics is very sinful. God may or may not answer the Bishop’s prayers, but it won’t be because of his idolizing and praying to Mary. If he honors it, it will be in spite of his sinful adoration of Mary.
Like it or not but Mary is the mother of God. Live with it. And for you information we Catholics do not pray to her. We ask her to be our referee
