I've heard that about Mary, too. However, I was in an RC church and saw a stature of Mary with a bunch of children at her feet, heads bowed, praying to her. The RCC calls her a co-redeemer with Christ. That's pure invention as the Bible says nothing of the kind. She was honored by being the mother of Jesus, but beyond that, she was nothing more than any other believer, saved by Jesus' blood.
Catholics may pray to Mary or any of the saints. Prayers asking them to pray to God for us. There is biblical justification for that. Only God is worshiped. Only Jesus is named as our redeemer.
If Mary is given to us as our spiritual mother (John 19:25-29) why wouldn't you ask for her help?
And if you truly follow Jesus why wouldn't you do good works as He commanded?
