Lauren,
 
It appears as though you have the Jubilee mathematics figured out correctly.
 
One question I have is are you thinking that the Second Coming will be this year?  It sounds like that's what you are saying.  But the Rapture has to happen at least seven years prior to the Second Coming.  How does the Rapture fit into the Jubilee counting?  Wouldn't one be correct in assuming that the prophecy of the end of the 85th Jubilee is relevant to the Jews, not the Church?  If the 85th Jubilee ends this year, 2008, then that would mean that the event marking the end of the 85th Jubilee is the Second Coming, right?
