The Pope's calendar for activities in October has one curious omission: there is no mention of any visit to, or activity in Assisi on October 27, although he will take part in a "Prayer in preparation of (sic) the Meeting in Assisi on October 26 at St. Peter's.
A recent report on EWTN also repeats the information (which seems not to have been adequately publicized) that Assisi III will not contain interreligious prayers. The final details of the event will be made public by October 18.
