Gaudentius had studied under Philastrius, and was a preacher in Italy and the Middle East. When Philastrius died around 387, the people of Brescia elected Gaudentius as bishop –evidently against his will. He was on pilgrimage to Jerusalem when Philastrius had died. The Catholic Encyclopedia states that “the people of Brescia bound themselves by an oath that they would accept no other bishop than Gaudentius; and St. Ambrose and other neighboring prelates, in consequence, obliged him to return, though against his will. The Eastern bishops also threatened to refuse him Communion if he did not obey.”
