I, too, have done some research into what these apparitions are saying. 
These are some of the areas that I have a problem with. The following are 
purported to have been spoken by the Madonna of Medjugorje:

1. She says that Muslims, Orthodox, Catholics, Marxists, etc. are all the 
same to her and her son. They are all her children and there should be no 
divisions.

2. She has shown people visions of heaven, hell and purgatory.

3. She says she will intercede for those who need healing.

4. She says she is in the wind; the wind is her sign. 

5. She allowed one girl to see and hug her dead mother.

6. She says she suffers for the sake of sinners and that we should offer 
our sufferings for the conversion of sinners.

7. She stresses saying the rosary. (This is the most constant thing she says 
no matter where she is "seen.")

8. She was angry and petulant at times with some of those who saw her 
because they dared to question what she said.

These are some of the specific areas that I, personally, found to be against 
what the Bible teaches and why I believe the apparitions are counterfeit and 
dangerous. I hope this is helpful to those who are wondering exactly why 
some people think this is demonic.
