As St. Thomas Aquinas say, she is the "go-between," the great matchmaker in the mystical marriage of Christ and the soul.
Show us one clear verse where it says Mary is our go-between...in other words we have to go through Mary to get to Christ.
No need for me to get in a protracted discussion with someone that it appears has already made up their mind I will continue to pray that the Holy Spirit comes into your heart.

Here is a link to the occurrences of the Greek word *adelphos*.
http://biblehub.com/greek/80.htm
The word *sister* (adelphe) in the Greek is the same.
http://biblehub.com/greek/79.htm
The word used is *brother* not *cousin*.
It can't mean a member of the same religious community in the context in which they occur, because then that would mean every man in Israel could be identified as Jesus' brother. So that would not identify Jesus as anyone in particular's brother.
It's not going to mean *brother in Christ* as that concept was not yet in place and the Jews, who knew Jesus as a Jew and knew His brothers as Jews, would not even begin to understand the new birth and what being in Christ meant.
They didn't even understand who JESUS was, much less being a *brother in Christ*.
The only definition left then, is to mean physical brother.
And it would not be *cousin*.
The word for *relative* that is used for Elizabeth is *suggenes*, not *adelphe*.
