Point out in the scriptures where the statement is right.
The Church determined which writings were the word of God and which were not.
This same Church founded by Our Lord and Savior, Jesus Christ, has venerated His mother for nearly 2000 years.
You would never even have seen the scriptures had not several monks (who by the way venerated the Mother of God) copied and recopied them for us.
So you have no scripture backing up the statement that "Mary's role in redemption is to lead ALL souls to her Son".
I gave you the scriptures that state it is the job of the Holy Spirit to reveal Christ, convict of sin and lead sinners to Christ for salvation.
And your church would never have had the Scriptures had it not been for the "Scribes and Pharisees" who serve as the arch-villains in your religion. So what makes you better than the Protestants you so easily look down on?
There is something very tiresome in hearing Catholics constantly preaching Judaism to the Protestants and Protestantism to the Jews.
