This is where Catholics tend to confuse non-Catholic Christians.
I can't tell from this complex sentence structure whether Mary (an obedient Jewish girl blessed by God) "obtained peace for all men!" or if her son ... "our Salvation", God Incarnate, the Lord Jesus Christ ... "obtained peace for all men!"
If you ascribe Mary as the one who obtained "peace for all men", then I really have a problem with crediting Mary with what Christ accomplished on the Cross. If you ascribe the Son of God, born of Mary as the one who obtained "peace for all men" ... then I can add my "Amen."
PS. I disagree about the rainbow:
"This is the sign of the covenant which I make between Me and you, and every living creature that is with you, for perpetual generations: I set My rainbow in the cloud, and it shall be for the sign of the covenant between Me and the earth. It shall be, when I bring a cloud over the earth, that the rainbow shall be seen in the cloud; and I will remember My covenant which is between Me and you and every living creature of all flesh; the waters shall never again become a flood to destroy all flesh. The rainbow shall be in the cloud, and I will look on it to remember the everlasting covenant between God and every living creature of all flesh that is on the earth. This is the sign of the covenant which I have established between Me and all flesh that is on the earth."

mary is the mother of our salvation
Mother of our savior
Lk 1:45 all generations shall call me blessed!
Actually this is an exultation of thanksgiving for having obtain thier eternal salvation!
