1. Medjugorje and Apparitions 

"And in the last days it shall be, God declares, that I will pour out my Spirit upon all flesh, and your sons and your daughters shall prophesy, and your young people shall see visions, and your old people shall dream dreams..." (Acts 2:17) 

1.0) Some people say that what is happening in Medjugorje is the work of satan, how do you respond? 
1.1) How does anyone know it's Mary that is appearing? No one I know has any idea what she looks like. 
1.2) Isn't believing in apparitions a form of worshipping Mary? 
1.3) Didn't the Pope say that people shouldn't go to Medjugorje? 

2. Living the Messages

2.0) For people who eat rice, how can they fast? Are they required to eat nothing for the breakfast and lunch ? If they can eat a little, how much is good for them to eat, and can they eat any time of the day? 
2.1) Our Lady mentions that God respects all religions, and that they are not separated in Heaven as they are on Earth. Since most religions do not have the Sacrament of Confession, and many do not celebrate the Eucharist, then how can we as Christians comply with Her request?  
2.2) How long does a fast last? Should it go for a full 24 hours? How does one do this properly?  
2.3) What exactly is meant by conversion? Conversion to Christianity? To living God's word and commandments? 

3. Issues of Catholic Faith

3.0)  If we are commanded to pray only to God through Jesus, why pray the Rosary? Isn't that worshipping Mary? 
3.1)  Many of the teachings and practices in the Catholic church lack support from scripture, why believe in them? 
3.2)  What does "catholic" mean? 
3.3)  Why pray before a piece of bread trapped in a Monstrance?
