The Greek Orthodox apparently know some Greek, and they agree with us, and disagree with you, on a whole lot of things. For one thing, they revere the Lord's Mother, and you seem to denigrate and minimize her as much as possible.
The roman catholic church came into existence around the 4th century
Not even remotely historically true, but part of the mythology that low-church Protestants like to promote.
Exactly when and how "around the 4th century" did this remarkable event happen?
You confuse a proper Biblical understanding of Mary with denigration.
Mary is the mother of Jesus (John 2:3).
She was favored by God (Luke 1:28) to be the mother of Jesus.
She is the wife of Joseph (Matthew 1:24)
She is the mother of his brothers and sisters (Matt 13:55-56).
She was a moral girl who kept her virginity (Luke 1:34) until after Christ was born (Matt 1:25).
She is blessed among women (Luke 1:42).
She was well versed in the OT (Luke 1:46-56).
She knew she was a sinner in that she and Joseph offered the sin and burnt offering as required by the OT Law (Luke 2:22 and Lev 12:8)
She was not worshiped by anyone (Matt 2:11) nor did she claim worship for herself as some of the Mary apparitions have claimed.
She tragically saw her Son crucified (John 19:25).
After Jesus was crucified we have record of her being present with the other believers (Acts 1:14).
Most importantly, she was a believer in Her Son for her salvation (Luke 1:46-47; Acts 1:14).
This is the proper respect that the Bible records about Mary.
It is worth remembering though, that Jesus is the focus of the New Testament. Not Mary as depicted in roman catholicism.
To focus any prayer or hope in Mary is to take that focus away from her Son.
That is the ultimate denigration of Mary and minimizes her Son.
