With the revised canonization process put in place by John Paul II there are now just 2 miracles required for canonization - one for beatification and then a second for canonization.
There is no specific record of formal miracles performed by St. Monica. She is known more for her devout faith, perseverance in prayer, and her role in the conversion of her son, St. Augustine. Monica's intercession is often sought by mothers and those facing family challenges.
Although nothing is really known about the life and death of the apostle Andrew, the apocryphal Acts of Andrew provides testimony of the miracles that came to be attributed to him. In a work typical of some of the hagiography of the time, Andrew is credited with some extravagant miracles. He healed the lame and blind, raised the dead, survived being placed amongst fierce animals, calmed storms and even defeated armies simply by crossing himself. He also caused the miscarriage of an unborn, illegitimate baby.
We have no record of any miracles performed by St. Monica. A legend was that miracles occurred as her relics were being moved to a new location, but such legends were quite routine during the Middle Ages.
Miracles were not required for declaring a person a saint in the early years of Chrisitianity. The person would have been declared a saint by popular acclamation to a bishop based on the lives and merits of the candidate. This was especially true if the person died the death of a martyr as it was felt that making this ultimate sacrifice for Our Lord would be an automatic designation of that person as a saint. Even today, miracles are not always a requirement for canonization, especially in the case of martyrs.
Saint Bernadette was visited by the Blessed Virgin Mary seventeen times. Mary told Bernadette to dig in the mud, and when Bernadette did a spring appeared. Many miracles happened when people used the spring.
Saint Benedict is a revered figure known for performing miracles during his lifetime, such as healing the sick and casting out demons. After his death, many believers attribute further miracles to his intercession, including healing the sick, protecting against evil forces, and bringing about conversions. These posthumous miracles have contributed to his lasting influence and recognition as a patron saint of various causes.
One of her miracles involved the total and almost instant cure of a woman with terminal cancer. A second miracle used for her canonization involved a total cure of another lady who was dying of leukemia.
Bernadette was responsible for many, many miracles and they continue even today. However, the Church must investigate and verify a number of miracles (today I believe it is two) before a person can be beatified and canonized a saint. Rather than listing the miracles here that were accepted by the Church in the cause of St. Bernadette I have inserted a link below that describes her complete canonization process and gives vivid accounts of the miracles that supported her cause.
he preformed many miricles for people and after he died Pope Gregory declared him as a saint!!
There were many miracles ascribed to St. Patrick. Three of those miracles are bringing a horse back to life, converting people who hated him, and telling a group of starving sailors to believe in God after which a herd of pigs appeared.
There are many, many saints and blesseds by the name of Jeanne so you will have to be more specific if you want a meaningful answer.
First of all, the saints do not perform miracles. The miracles are performed by God at the request of the saint. Each individual case is based on its own merits. Usually 2 miracles are required, one for beatification and one for canonization. If the person died as a martyr, one or more miracles may be dropped. Other things can also be taken into consideration such as bilocation. incorruptibility, stigmata, heavenly perfume, etc.
