Catholic saints are individuals recognized by the Catholic Church for their holiness and virtue. They are often seen as role models for the faithful and are believed to intercede with God on behalf of people. Saints can be canonized after a thorough investigation of their lives, miracles, and contributions to the Christian faith. Many saints have specific feast days celebrated throughout the year, and they are often associated with particular causes or professions. For example, Saint Francis of Assisi is the patron saint of animals, while Saint Jude is known as the patron saint of lost causes. These figures inspire devotion and are honored in various ways, including prayers and artwork.
