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?
Spiritual mother? Jesus merely told John to take his mother, apparently widowed, into his house to care for her after he died. He was doing his duty as a good son. There are questions as to why Jesus didn't place her with one of his younger brothers but possibly it was because none of them were believers at the time.
Besides, talking to the dead is evil:
Deut 18:11 ... or casts spells, or who is a medium or spiritist or
who consults the dead.
12 Anyone who does these things is detestable to the LORD, and because of these detestable practices the LORD your God will drive out those nations before you.
God didn't give any church the authority to turn this evil practice into a good one. There is no provision in the Bible for praying to any dead person. We pray to God and God alone.
