Yes, I see a problem with the Marian apparitions since they focus attention on Mary and not on the Lord. Mary's role in Scripture is limited and she is not even mentioned after Acts 1:14.
What promises does this Mary give to the faithful? Promote and honor her and she will alleviate their suffering and other heretical teachings that place her on equal footing with the Lord. This is sheer blasphemy. Even Peter your first Pope was not so arrogant as to take credit for what only faith in the Lord could accomplish through the Holy Spirit.
Mary is no greater than any other member of the Body of Christ, even Jesus said there is none born of women that was greater than John the Baptist but the least in the kingdom is greater than John.
