Pope Francis on Sunday announced that he would elevate 21 churchmen to the high rank of cardinal, again putting his mark on the group that will one day choose his successor after his death or resignation.

The ceremony to install them, known as a consistory, will be held on September 30, the 86-year-old Francis announced during his noon prayer to pilgrims and tourists in St. Peter’s Square.

It will be the ninth consistory called by the pope since his election 10 years ago as the first pontiff from Latin America.

The new cardinals come from countries, including the United States, Italy, Argentina, Switzerland, South Africa, Spain, Colombia, South Sudan, Hong Kong, Poland, Malaysia, Tanzania, and Portugal.

Eighteen of the 21 are under 80 and will be able to enter an eventual secret conclave to choose the next pope. They are known as cardinal electors.

After the September consistory, there will be 137 cardinal electors, about 73 per cent of them chosen by Francis. This increases the possibility that the next pope will share his vision of a more progressive, inclusive Church.

Francis has also increased the possibility that the next pope will come from Asia or Africa, having consistently named cardinal electors from those continents and giving less importance than his predecessor to countries in Europe.

Whether the pope will name even more cardinals depends on how long he lives.

Francis spent nine days in hospital after surgery for an abdominal hernia last month. His recovery is going well and he is due to visit Portugal from August 2 to 4 and Mongolia from August 31 to September 4.

The other three new cardinals, who are 80 or over and too old to vote in a conclave, were named to thank them for their long service to the Church.

All cardinals, regardless of their age, are allowed to take part in pre-conclave meetings, known as General Congregations, giving them a say in the type of person they think the younger cardinals should choose.
