Pope Francis and members of the international Council of Cardinals advising him on Church governance once again discussed ways to improve the process of identifying the best priests to become bishops.

"The cardinals reflected broadly on the spiritual and pastoral profile necessary for a bishop today," said Greg Burke, director of the Vatican press office.

Meeting with Pope Francis between September 12-14, they also discussed "the theme of the Holy See's diplomatic service and the formation and tasks of apostolic nuncios with particular attention to their great responsibility in the choice of candidates for the episcopacy," Burke said in a statement.
