Beatification (from Latin beatus, "blessed" and facere, "to make”) is a recognition accorded by the Catholic Church of a dead person's entrance into Heaven and capacity to intercede on behalf of individuals who pray in his or her name. Beati is the plural form, referring to those who have undergone the process of beatification.
Since the reforms of 1983, as a rule, one miracle must be confirmed to have taken place through the intercession of the person to be beatified. Miracles are almost always unexplainable medical healings, and are scientifically investigated by commissions comprising physicians and theologians.
The feast day for a beatified person is not universal, but is celebrated only by territories, religious institutes, or communities in which the person receives particular veneration. For instance, Saint Kateri Tekakwitha was especially honored in the United States and Canada during her time as Blessed. John Duns Scotus was honored among the Franciscans, in the Archdiocese of Cologne and other places. Similarly, veneration of Blessed Chiara Badano is particular to the Focolare movement.
Pope John Paul II (18 May 1920 – 2 April 2005) markedly changed previous Catholic practice of beatification. By October 2004, he had beatified 1,340 people, more than the sum of all of his predecessors since Pope Sixtus V (1585–1590), who established a beatification procedure similar to that used today.
John Paul II's successor, Pope Benedict XVI, personally celebrated the Beatification Mass for his predecessor at St. Peter's Basilica, on the Second Sunday of Easter, or Divine Mercy Sunday, on 1 May 2011, an event that drew more than one million people.
