It's no different than asking a saint to intercede on your behalf, which has been going on for about 1700 years. Nothing special here. Asking Mary to intercede on your behalf is not much different than asking other Christians to pray for you.
Mary didn't die for anyone and she can't intercede to God for anyone. Only Christ can do that.
Mary is beloved of God because she bore His one son. She was not just a vessel, to be used and then discarded. He chose her as the mother of His son. Isn't it therefore logical to conlude that she is important to God?
Give me the scriptures that say we should ask Mary for help.
Jesus ridiculed the traditions of men. Praying to Mary or to the dead goes directly against scripture as I already pointed out to you. Any tradition that is contrary to scripture is false.
Heb. 4:16 Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need.
Until you deal with these scriptures and somehow reconcile your beliefs with these (which you can't), you don't have a leg to stand on.
