Vatican to SSPX: You Have One Month, or Else!

The Vatican on Friday told an ultra-traditionalist Roman Catholic splinter group they must accept non-negotiable doctrinal principles within a month or risk a painful break with Rome that would have "incalculable" consequences.

The ultimatum was issued after a two-hour meeting between Swiss-born Bishop Bernard Fellay, leader of the dissident Society of Saint Pius X (SSPX) and U.S. Cardinal William Levada, head of the Vatican's doctrinal department.
