The coding has nothing to do with people's predictions or the armageddon based concepts but to do with the protection of the spiritual information from the wrath of Romans.Barbara Theiring explores this fundamentally and later people like Baigent and Liegh who did great investigative work but made some significant errors and also some significant discoveries. Barbara, a theologian of note, looked at the entry coding "for those who have ears to hear etc". Unfortuantely intellectual discovery has rarely suitd the RCC. As for the soothsayers and those who think of Nostradmus as some great force..forget that and start to read Theiring to answer your questions. As for 911 that was certainly an evangelist's reward.
