Pope Leo pleads with breakaway Catholic group not to commit 'sin of extreme gravity'

Pope Leo XIV issued an extraordinary last-minute plea Tuesday to a breakaway traditionalist Catholic group to abandon plans to consecrate four bishops without Vatican approval, warning the move was a "sin of extreme gravity" and could deepen a decades-old split with the Church.

In a letter addressed to the Rev. Davide Pagliarani, leader of the Society of St. Pius X, Leo urged the group to reconsider before Wednesday's planned ceremony in Econe, Switzerland, saying it would place the bishops involved outside the Church’s communion.
