It really happened on March 12 in 1622. Pope Gregory XV capped off the Counter-Reformation era by canonizing four great reformer saints: St. Ignatius of Loyola, St. Francis Xavier, St. Teresa of Avila, and St. Philip Neri and the patron saint of Madrid, St. Isidore the Farmer. In Rome, they were most proud of St. Philip Neri, the one Roman among the canonized, thus the quip, "Four Spaniards and One Saint." Jesuits around the world celebrate this day as a day of thanksgiving, according to this website:
A little-known day of Jesuit thanksgiving was celebrated on March 12 to mark the canonizations of two of the most famous Jesuits: St. Ignatius of Loyola and St. Francis Xavier. Every year on that date, each Jesuit offers a special prayer or Mass of Thanksgiving for the gift of the saints’ canonizations, which occurred on March 12, 1622 — 66 years after the death of Ignatius and 70 years after the death of Xavier.
The founder of the Society of Jesus, Ignatius lived most of his priestly life in a small room in Rome, directing the newly founded Society. Francis Xavier, one of the Society’s most well-known missionaries, lived most of his Jesuit life traveling around Asia, preaching and baptizing.
Pope Gregory XV was responsible for canonizing the two Jesuits, and he held religious orders in high esteem. The pope was educated by the Jesuits at the “Collegio Romano,” the university founded by Ignatius in Rome that is now known as the Gregorian University.
On the same day Ignatius and Francis Xavier were canonized, Pope Gregory XV also canonized Teresa of Avila, reformer of the Carmelites; Philip Neri, founder of the Oratorian Fathers; and Isidore of Madrid, a simple but devout farmer, now patron of farmers, peasants, day laborers and rural communities.
The grouping of these five dissimilar saints took some by surprise and illustrated that there is no mold for being holy or even for becoming a canonized saint. Pope Gregory XV was never canonized, but he did keep his connection to the Jesuit saints. The pope was buried in the Church of Saint Ignatius in Rome when he died in 1623.
Blessed John Henry Newman wrote of St. Philip Neri, his patron as an Oratorian:
And when he died, a continued stream of people, says his biographer, came to see his body, during the two days that it remained in the church, kissing his bier, touching him with their rosaries or their rings, or taking away portions of his hair, or the flowers which were strewed over him; and, among the crowd, persons of every rank and condition were heard lamenting and extolling one who was so lowly, yet so great; who had been so variously endowed, and had been the pupil of so many saintly masters; who had the breadth of view of St. Dominic, the poetry of St. Benedict, the wisdom of St. Ignatius, and all recommended by an unassuming grace and a winning tenderness which were his own.
Of St. Isidore the Farmer, Loyola Press notes:
Isidore was born in Madrid, Spain, and farming was to be his labor, working for the same landowner his whole life. While he walked the fields, plowing, planting, and harvesting, he also prayed. As a hardworking man, Isidore had three great loves: God, his family, and the soil. He and his wife Maria, who is also honored as a saint, proved to all their neighbors that poverty, hard work, and sorrow (their only child died as little boy) cannot destroy human happiness if we accept them with faith and in union with Christ. Isidore understood clearly that, without soil, the human race cannot exist too long. The insight may explain why he always had such a reverent attitude toward his work as a farmer.
Isidore and Maria were known for their love of the poor. Often they brought food to poor, hungry persons and prayed with them. During his lifetime, Isidore had the gift of miracles. If he was late for work because he went to Mass, and angel was seen plowing for him. More than once he fed hungry people with food that seemed to multiply miraculously. He died after a peaceful life of hard labor and charity.
