The Apostles never asked Mary to pray for anyone. I've studied all the Episodes of Paul, Peter, James, John, and there's nothing mentioned about Mary. Everything is about Jesus.

You may be right! When Jesus said, "When two or three of you gather in my name..." he clearly forgot to include, "Except you cannot gather with my mother. She doesn't count." Oh, wait a minute! She did gather with the Apostles on Pentecost, so I guess she wasn't excluded after all.
Why does it bother you that Catholics pray with both the living and those who have passed on? It wasn't a requirement, after all. No one is insisting you pray with anyone, let alone those who have passed on.
