1 Timothy 2:5

For there is one God, and one mediator between God and men, the man Christ Jesus

I praise thine exalted privilege of being truly Mother of God, ever Virgin, conceived without stain of sin, Co-Redemptrix of the human race.

The idea Mary is the "Co-Redemptrix" is a Roman Catholic tradition.

Mark 7:9

And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
