Come on now. Do you follow the no meat eating on Fridays during Lent? Or the praying to Mary? How about the "transforming" of water and wine to christ's blood? Should I go on?
1. Let's say you have a class of fourth graders who want to do something charitable, say donate money to a charity or something. The first thing they have to think about is where they are going to get the money. You ask them, and nobody knows. Then you ask if they had bought any soda from the vending machine this week. Almost all of them raise their hands. Then you say 'well, why don't we use that money?'
Lent is the same way. Eating no meat on Fridays is a tradition more than anything, but it is a way to start thinking. Last Lent, I ate meat on Fridays, but I also tried to do something different than I normally do. There is a point to abstaining from meat on Fridays. You give something up (or add something new) to teach yourself a lesson.
2. Praying to Mary...well, you can put just about any name there and it would be the same. The common conception of prayer is silly, as many people on this site have pointed out. I ask for something and God will either give it to me, not give it to me, or tell me to wait.
Yeah, right. I think I figured out this delusion when I was in second grade.
Prayer isn't asking God(or anyone else) for what you want. The part of mass where we say a prayer and then say 'lord, hear our prayer' isn't praying at all. Prayer is about silence. You put forth what you think you need or want, and that's it. It's not about asking for anything. It's written in the Gospels (either Luke or Matthew, I'm not sure).
3. This one is quite possibly the easiest one to explain...but the hardest to experience. Does the wine and bread turn into Jesus' body and blood? Do I even need to answer that question?
Yes of course it does. No wait, it actually is. We dug up Jesus and put him in the flour and the grapes. Now we need you to throw up now, so we can resuse it.
^Being stupid.
It's not anything special. It's bread and wine. Stale bread and bad wine if you ask me. It's just ordinary bread and wine, that earth has grown and human hands have made. It doesn't change.
That's the whole point.
Believing that the ordinary is actually extraordinary is not uncommon. You see it in movies all the time. The hero is just an ordinary guy (or gal) until they realize that they can be extraordinary. The transformation of the bread and wine is the same concept.
