Here's an interesting thing ... this is the best thing I've heard so far from the Catholic Church.  The Vatican tells the Catholics how they should behave.  What's okay and what's not.  Now in one of the great sacraments, Mass, they drink wine and eat bread.  Congregations that sets these rules decides that it's acceptable Eucharistic matter if it was made from genetically modified organisms it was okay, but if it was gluten-free, apparently it doesn't work.  It's the best thing that so far has come out from the Catholic Church about this.
