Yes, there is because nowhere in Scripture are we ever commanded to pray to anyone but God.
And the prayers to Mary go well beyond simply asking her to pray for us.
Those whose physical bodies have died have gone beyond out ability to contact them. Attempting to do so is condemned by God, but clearly that doesn't stop Catholics from practicing or teaching it as there are many things outright forbidden by God in Scripture that the Catholic church practices and rationalizes away.
And actually, there is no rational basis for praying TO Mary. There's nothing she's going to do for people that God Himself wouldn't do because since God's will is done in heaven, she's not going to be praying against that will.
Luke 11:1-13 Now Jesus was praying in a certain place, and when he finished, one of his disciples said to him, “Lord, teach us to pray, as John taught his disciples.” And he said to them, “When you pray, say:
“Father, hallowed be your name. Your kingdom come. Give us each day our daily bread, and forgive us our sins, for we ourselves forgive everyone who is indebted to us. And lead us not into temptation.”
And he said to them, “Which of you who has a friend will go to him at midnight and say to him, ‘Friend, lend me three loaves, for a friend of mine has arrived on a journey, and I have nothing to set before him’; and he will answer from within, ‘Do not bother me; the door is now shut, and my children are with me in bed. I cannot get up and give you anything’? I tell you, though he will not get up and give him anything because he is his friend, yet because of his impudence he will rise and give him whatever he needs.
And I tell you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. For everyone who asks receives, and the one who seeks finds, and to the one who knocks it will be opened. What father among you, if his son asks for a fish, will instead of a fish give him a serpent; or if he asks for an egg, will give him a scorpion? If you then, who are evil, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!”
Scripture forbids SUMMONING spirits or the dead. Catholics never do that. Prayers addressed “to” Mary or other saints are not adoration, but requests for prayers.
You are stuffed full of Protestant propaganda. You believe that Catholics believe things they don’t believe, and do things they don’t do.
Protestants propagandized against devotion to the saints because they wished to ransack the monasteries and churches, which they did all over Europe and in England. The result was a century of debauchery and war.
There isn’t a smidgen of evidence in Scripture for the ugly, repulsive doctrine that my mother, who loved me and prayed for me all my life, is now a doorstop.
