Pope Francis announced Sunday that he will create 21 new cardinals Aug. 27, including Bishop Robert W. McElroy of San Diego, long seen as one of his key allies in the United States.

Also on the list is Nigerian Bishop Peter Ebere Okpaleke, appointed to Ahiara by Pope Benedict XVI in 2012.

All the cardinals of the world are set to be in Rome for the occasion. They will already be there for an Aug. 29-30 session to reflect on the new Vatican’s constitution that goes in effect June 6. This will be Pope Francis’s eighth consistory for the creation of new cardinals.

Of the new crop of cardinals, 16 will be able to participate in the conclave that will eventually choose Pope Francis’s successor. The other five are over the age of 80 making the title mostly an honorary one.
