San Germano, bishop of Auxerre in the 5th century, is a prominent figure in the history of the Gallican Church. Born into a noble Roman family, he initially embarked on a forensic career, distinguishing himself for his skills. His life took a radical turn when, elected bishop by popular acclamation, he abandoned worldly life to dedicate himself entirely to the service of God and his community.
He was a zealous pastor and a defender of the orthodox faith, strenuously fighting the Pelagian heresy that denied the importance of divine grace. He made several trips to Britain to counter the spread of this doctrine, achieving remarkable successes. His work was not limited to the theological sphere; he was also a man of great charity, attentive to the needs of the poor and the oppressed.
The veneration of San Germano spread rapidly, as evidenced by the construction of numerous churches and monasteries dedicated to him. He is remembered for his miracles, his wisdom and his profound spirituality. The two keys, often associated with his iconography, symbolize his spiritual power and his episcopal authority, while the book represents his erudition and his commitment to defending the truth. His liturgical memorial occurs on July 31.
