The problem is not with those ask the Father to have so and so (Mary) pray for them.
The problem is in praying to Mary.
It is the same with our blessed mother. Jesus gave her to all his disciples. She is our spiritual mother. For all those that can walk their spiritual path by themselves, God Bless them. My spiritual Mother was there for me, she brought me to Jesus. Thank God.
I understand when people don't have the same faith walk as mine, it does hurt me however when our beliefs and experiences our either misinterpreted or slandered for lack of understanding. My Catholic church has been around for over 2008 years because God allowed it, Luther rebelled because God allowed it. It is as simple as that. The enemy will always attack the most important to God's kingdom, so let's remember to love each other regardless of our differences. Please.

Why would we give our petition to God, asking Him to give it to Mary so she could give it back to Him? The reason we ask Mary to bring them to Him is because of James 5:16.
