Quotes of Popes declaring Mary worthy of worship:
"Do you ask me, is Mary willing to assist you? Does she really take an interest in your welfare? Or is she so much absorbed by the fruitation of God as to be indifferent to our miseries? "Can a woman forget her infant so as not to have pity on the fruit of her womb"? (Isaiah 49:15), Even so Mary will not forget us" "Faith of our Fathers, By Cardinal James Gibbons, Archbishop of Baltimore, page 225, 1893 edition.
Let's see what Isaiah really says:
"Can a woman forget her sucking child, that she should not have compassion on the son of her womb? YEA, they may forget, Yet I will not forget thee" Isaiah 49:15
"God has entrusted the keys and treasures of heaven to Mary." Thomas Aquinas
"Holy Scripture was written to Mary, about Mary, and on account of Mary." St. Bernard
"No one ever finds Christ but with and through Mary. Whoever seeks Christ apart from Mary seeks Him in vain." St. Bonaventure
"What will it cost you, oh Mary, to hear our prayer? What will it cost you to save us? Has not Jesus placed in your hands all the treasures of His grace and mercy? You sit crowned Queen at the right hand of your son: your dominion reaches as far as the heavens and to you are subject the earth and all creatures dwelling thereon. Your dominion reaches even down into the abyss of hell, and you alone, oh Mary, save us from the hands of Satan." Pope Pius Xl
"Mary, not one of thy devout servants has ever perished: may I, too, Be saved!" Pope Benedict XV
"O Mary Mother of Mercy and Refuge of Sinners! We beseech thee to look with pitying eyes on poor heretics and schismatics. Do thou, who art the Seat of Wisdom, enlighten the minds wretchedly enfolded in the darkness of ignorance and sin, that they may clearly recognize the Holy, Catholic, Roman Church to be the only true Church of Jesus Christ, outside of which neither sanctity nor salvation can be found. Call them to the unity of the one fold, granting them the grace to believe every truth of our holy faith and to submit themselves to the Supreme Roman Pontiff, the Vicar of Jesus Christ on earth, that, thus being united with us by the sweet chains of charity, there may soon be but one fold under one and the same Shepherd; and may we all thus, O Glorious Virgin, exultantly sing forever: ‘Rejoice, O Virgin Mary! Thou alone hast destroyed all heresies in the whole world!’ Amen." (Pope Pius XII, The Raccolta, Benzinger Brothers, Boston, 1957, No. 626).
May 7, 1997 (David W. Cloud, Fundamental Baptist News Service, 1701 Harns Rd., Oak Harbor, WA 98277) - On May 7 Pope John Paul II dedicated his general audience to "the Virgin Mary" and urged all Christians to accept Mary as their mother. He noted the words spoken by Jesus on the cross to Mary and to John--"Woman, behold thy son!" and "Behold thy mother!" (John 19:26,27), and he claimed that in this statement "IT IS POSSIBLE TO UNDERSTAND THE AUTHENTIC MEANING OF MARIAN WORSHIP in the ecclesial community ... which furthermore is based on the will of Christ" (Vatican Information Service, May 7, 1997).
John Paul II underlined that "the history of Christian piety teaches that MARY IS THE PATH THAT LEADS TO CHRIST, and that filial devotion to her does not at all diminish intimacy with Jesus, but rather, it increases it and leads it to very high levels of perfection." He concluded by asking all Christians "to make room (for Mary) in their daily lives, ACKNOWLEDGING HER PROVIDENTIAL ROLE IN THE PATH OF SALVATION" (Ibid.).
