 Upon canonization, the Pope declared St. Maximilian Kolbe as a confessor, and a martyr of charity.The miracles that were used to confirm his beatification were the July 1948 cure of intestinal tuberculosis in Angela Testoni, and in August 1950, the cure of calcification of the arteries/sclerosis of Francis Ranier; both attributed to Kolbe's intercession by their prayers to him.After his canonization, a feast day for St. Maximilian Kolbe was added to the General Roman Calendar.
