Vatican to say next month when John Paul II will become saint

(CNN) -- The Roman Catholic Church will announce next month the date when the late popes John Paul II and John XXIII will be canonized, Vatican Radio reported Wednesday.

The canonization dates for the two former pontiffs will be announced on September 30, the radio service reported, citing Cardinal Angelo Amato.

Pope Francis announced last month that his two 20th century predecessors would be declared saints.

John Paul was pope from 1978 until his death in 2005, drawing vast crowds as he crisscrossed the globe. The third-longest-serving pope in history, died at the age of 84 after suffering from Parkinson's disease, arthritis and other ailments for several years.

Pope John XXIII was famed for calling the Second Vatican Council in 1962, which ushered in great changes in the Roman Catholic Church's relationship with the modern world. He was pope from 1958 to 1963.
