1. What has been the Church's method of canonizing saints in the past?

4. Has the Church retracted canonization of saints in the past?
Basically, the process is similar to the process in use for the preceding millenium or so, consisting primarily of research and the presentation of evidence of sanctity, with one significant change made by John Paul II, which was to suppress the "Devli's Advocate," who presented a case against the canonization of the person(s) in question. The number of required miracles was also lowered. However, this in itself isn't really a problem, as popes have from time to time entirely set aside the need for a verified miracle (St. Thomas More, canonized in 1935 by Pius XI, being one example).
I don't know if the average time between death and canonization is faster on the average for all saints. Many well-loved saints were canonized very quickly, e.g., St. Francis of Assisi died in October 1226 and was canonized less than two years later in July 1228. However, in the case of popes, then the speed of canonization certainly seems to have increased. St. Pius V died in 1572 and was not beatified for another 100 years (1672), and canonized another 40 (1712) years after that. St. Pius X died in 1914, was beatified in 1951 and canonized in 1954. The other beatified popes since Trent are Bl. Innocent XI (d. 1689, b. 1956); Bl. Pius IX (d. 1878, b. 2000); Bl. John XXIII (d. 1963, b. 2000); and Bl. John Paul II (d. 2005, b. 2011).
To my knowledge no solemn canonization has ever been retracted. Some saints have been removed from the General Calendar, like St. Christopher, but that is different - they're still saints.
