First off, there have been 266 popes and you have not specified which one you are referring to. Secondly, a cardinal does not have to perform miracles to be elected pope. You are confusing a papal conclave with the canonization process for naming saints.
Two, actually. If the Pope finds that you did in fact make those miracles, he will proclaim you a saint.
There have been 15 popes named Benedict and none of them are noted for miracles.
In 1984 that was changed to 2 miracles and the pope has the prerogative to drop that to one miracle in certain cases.
Normally, one miracle must be proven for beatification and one additional for canonization. Under extraordinary conditions(martyrdom, for example) the pope can drop one miracle from the requirement.
Two miracles attributed to Pope John Paul II were the healing of a French nun, Sister Marie Simon-Pierre, from Parkinson's disease in 2005 and the healing of a Costa Rican woman, Floribeth Mora, from a brain aneurysm in 2011. These miracles were cited as evidence for his canonization as a saint in the Catholic Church.
Odo was never the pope.
Saladin was never a pope.
Saladin was not a pope.
A priest could only become pope if he is elected by the cardinals in conclave.
To become a pope, one must be at least 18 years old.
You become a pope when you are elected as such in a secret conclave held in the Sistine Chapel of the Vatican to replace a pope who as either died or retired.
Pope Saint Zachary, who served as pope from 741 to 752, is attributed with several miracles, notably his ability to heal the sick and perform exorcisms. While specific accounts of his miracles are not extensively documented, his reputation for sanctity and divine intervention contributed to his veneration as a saint. He was particularly revered for his pastoral care and guidance during a tumultuous period in Church history. His canonization and continued remembrance reflect the impact he had on the faithful during his life and beyond.
