François de Sales (1567–1622), was a Savoyard cleric born at the château of Sales near Thorens-Glières. Bishop of Geneva, resident in Annecy, he was proclaimed a saint and doctor of the Catholic Church.
Coming from a noble family, he chose the path of faith by dedicating his life to God and renounced all his titles of nobility. He became one of the most highly regarded theologians of his time. This great preacher became bishop of Geneva and founded, with the Baroness Jeanne de Chantal, the religious order of the Visitation.
He exerted a marked influence in the Catholic Church and was very much listened to by the holders of temporal power, the Regent of Savoy Christine of France and the kings Henri IV and Louis XIII of France.
He was a man of writing, leaving behind an important work that testifies to his vision of life. Since 1923, the Catholic Church has considered him to be the patron saint of journalists and writers because of his use of printing. His publications are among the world’s first Catholic newspapers.
