Catholics are correct when it comes to the Virgin Mary

Mary is the Mother of God: My opponent is actually advocating the position of a 5th century heresy known as "Nestorianism". He claims that Mary was merely the mother of Christ"s "human" nature. This is to deny the person of Jesus Christ, a historical person who walked the Earth, as being both fully human and fully divine. The claim that Mary did not give birth to the unified person of Jesus Christ asserts the separation of Christ"s human nature from his divine nature. This creates two separate and distinct persons. One of those persons being divine and the other human. This is a Christological heresy. In fact, John Calvin and Martin Luther both supported the divine Maternity of Mary. Denying that Mary is the mother of Jesus (who was fully a human person and fully God), places doubts and theological problems on Jesus" divinity, and therefore the whole concept of Christianity. Mary IS the Mother of God. She was the Mother of Jesus when He was conceived in her womb, when He was carried and nurtured in her womb, and she was the mother of Jesus throughout his whole life on earth. She was given the title of "Blessed", "Highly Favored", and it is through her Fiat (her, "Let It be done unto me according to your will), her obedience and willingness to accept this"that we have salvation in this world, through her Son Jesus Christ, who is God! (Except according to my opponent, He is not God whenever it is convenient). Here is the big point my opponent is missing in his logic: Mary is the Mother of God in the sense that she carried in her womb a divine person"Jesus Christ. Jesus Christ is God "in the flesh" (2 John 7, John 1:14). A woman is someone"s mother if she carried the person in her womb, or if she was the woman contributing half of his genetic matter or both. Mary did both of these; she not only carried Jesus in her womb but also supplied ALL genetic material for his earthly body. Joseph did not. That last point quickly defeats my opponents citation of Jesus being lost in the temple and being in his Father"s house. For God truly was Jesus" father, and Joseph truly was not. Additionally, Jesus can obtain his lineage to the House of David through Mary and not Joseph. Mary is Christ"s mother, the logical syllogism that follows is that she is also the Mother of God: Mary is the Mother of Jesus Jesus is God Mary is the Mother of God I would love for my opponent to refute that. Please, tell us all at what point on Earth that Jesus was not God and Mary was not His mother? Even in the womb, Elizabeth refers to Mary as "the mother of my LORD" (Luke 1:43). Elizabeth is recognizing that the person inside Mary"s womb is GOD. One cannot escape this logical syllogism. Only recently have Protestants and Fundamentalists refuted this; for as mentioned earlier even Luther and Calvin supported her divine maternity. The reason for this divergence is because Protestantism brought on thousands of different interpretations of Scripture and Doctrine, which continues to increase today. This goes against Christ establishing ONE Church (and not giving His disciples a Bible, which came hundreds of years later".by the Bishops of the Catholic Church) and against the Holy Spirit through Paul urging that "there be no divisions among you" (1 COR 1:10). Apostolic Tradition and Teaching authority (see Matthew 16:18, Matthew 18:17) quells divisions coming from endless "infallible" interpretations of Scripture that Protestants have. But this is not a debate about Sola Scriptura and Church authority, so moving on. This is not new, by the way, and I suggest my opponent read more carefully into his Christian heritage. This is not only in reference to the position of the early Protestant Reformers, but also of our early Church Fathers. Regarding the Nestorian heresy, even as early as 189 AD we have quotes from the early Christians regarding Mary"s divine maternity: "The Virgin Mary, being obedient to his word, received from an angel the glad tidings that she would bear God" " St. Irenaeus (Against Heresies, 5:19:1) And finally from the Early Fathers I will cite Cyril of Alexandria:R32;R32; "I have been amazed that some are utterly in doubt as to whether or not the holy Virgin is able to be called the Mother of God. For if our Lord Jesus Christ is God, how should the holy Virgin who bore him not be the Mother of God?" (Letter to the Monks of Egypt"1 [A.D. 427])."R32;R32;"This expression, however, "the Word was made flesh" [John 1:14], can mean nothing else but that he partook of flesh and blood like to us; he made our body his own, and came forth man from a woman, not casting off his existence as God, or his generation of God the Father, but even in taking to himself flesh remaining what he was. This the declaration of the correct faith proclaims everywhere. This was the sentiment of the holy Fathers; therefore they ventured to call the holy Virgin "the Mother of God," not as if the nature of the Word or his divinity had its beginning from the holy Virgin, but because of her was born that holy body with a rational soul, to which the Word, being personally united, is said to be born according to the flesh" (First Letter to Nestorius"[A.D. 430])."R32;R32;"And since the holy Virgin corporeally brought forth God made one with flesh according to nature, for this reason we also call her Mother of God, not as if the nature of the Word had the beginning of its existence from the flesh" (Third Letter to Nestorius"[A.D. 430])."R32;R32;"If anyone will not confess that the Emmanuel is very God, and that therefore the holy Virgin is the Mother of God, inasmuch as in the flesh she bore the Word of God made flesh [John 1:14]: let him be anathema" (The majority of this point was derived from the following website, in addition to the citations of the Early Church father"s quotations: https://www.catholic.com...) Here is a quick quote from Luther: On the newborn Jesus: "They must have marveled that this Child was the Son of God. He was also a real human being. Those who say that Mary was not a real mother lose all the joy. He was a true Baby, with flesh, blood, hands and legs. He slept, cried, and did everything else that a baby does only without sin." ^http://www.christianitytoday.com... Additional Citations and Suggested Reading for this argument: http://www.newadvent.org... - For more on the Nestorian Heresy Second Point: First of all, the "Trinity" is "an invention" of the Catholic Church, either. It is not explicitly mentioned nor explicitly talked about in Scripture. We have the doctrine of the Trinity thanks to Christ's Church he established, and this doctrine was cemented before there even was a Bible. Do you want to deny the Trinity? Or would you rather thank Catholic Theologians and Bishops for acting on the Holy Spirit's will and guidance? In short (due to character limit), Mary brought Christ into the world through her "Fiat" (her willingness and obedience, "Let it be done unto me according to your will"). She is not a rival to Christ, but one of the major ways in which God chooses to administer His graces into the world. Just like how you can preach the Gospel and "save someone" and by virtue "save yourself" (1 COR 9:22, for example). Are we neglecting Christ by being a channel for His peace and grace? No. It does not logically follow. Third point: Jesus commands us to keep all the commandments (Matthew 19:17, John 14:15), and the Fourth Commandment is to Honor Your Mother and Your Father (Exodus 20). Jesus is our brother (Hebrews 2:11), and Mary is His Mother. Therefore, Mary is our Spiritual Mother. You admit she is a saint (which means she is in heaven). How do you know this, it is not in Scripture? Of course that is rhetorical. I know how you know it brother. You know it in your heart. Scripture says that "all generations shall call {her} blessed!".
