Am I therefore become your enemy, because I tell you the truth? (Galatian 4:16)
Summarizing the discusion:
1) Mother of God theory contradicts Heb 7:2-3 which states Melchisedec has the common points with Son of God because both has no Mother no Genealogy.
People of [Mother of God] are so much obssessed with Goddess Worship. If the neutral people who do not believe Bible, and worship no goddess, they can interpret the sentence neutrally and would tell that such comparison wouldn't be possible if the writer had belief that Son of God has the Mother. He compared Melchisedec to Son of God, on the bases that Son of God has no father, no mother, no genealogy, and is king of righteousness, king of peace, which are the common points.
2. Mother of God theory contradicts Trinity because it denies God the Father is God, but claims only God the Son is God in a certain human created sentence (phrase): Mother of God.
3. It denies Holy Spirit is God, because they say Mary is Mother of God, then she is not Mother of Holy Spirit, and thereby Holy Spirit is not God in their own sentence, which means God is God only in the limited space and in the limited sentences, while True God is everywhere.
4. [Mother of God] denies the Pre-existence of Jesus before Mary, while Jesus Himself says Before Abraham was, I am (Jn 8:58). Jesus was almost stoned at that time by Pharasees, whose spiritual descendants may be here on this board.
5. [Mother of God] results in the funny comedy that Mother of God becomes a bride or wife of Son of God, which is a heretic comedy!
6. Nobody in the Bible calls Mary as Mother of God. Which means only pagan believers might have started to call that way.
7. Revelation which shows the future of this world mentions the Blessed name of the Blessed Mother of God at all, which means the most of the people who calls Mother of God may be going to the Lake of Fire!
8. False Christians claim that they are the true believers, but often they disguise themselves as angels of the Light, and lead to Goddess Worship.
9. [Mother of God] exalts the human being, the created, on top of Creator, God, which is absolutely a Heresy!
10. [Mother of God] conveniently claim that the humanity of Jesus didn't exist before Mary, but Mary contributed for that humanity, then she became Mother of Divinity, Mother of God. The truth is that Mary can be the mother of the humanity of Jesus, not for the divinity which existed before Mary, before the creation of the World. If she is not the mother of the divinity, then she should not be called Mother of God.
I know your logic, and know also that you are saying it within the limited sense of Mother of God, but you must recognize that Bible doesn't say so, because it exalt a woman as goddess on top of God, which is heresy!
Come out of Goddess worship theory, if you are true Christians!
