Peter Faber was a 16th-century Savoyard priest and theologian who helped found the Society of Jesus alongside Ignatius of Loyola and Francis Xavier. Born in 1506 in the Duchy of Savoy, he studied in Paris, where he formed deep spiritual bonds with his future companions. Known for his extensive travels across Europe, he focused on personal reformation and spiritual guidance rather than theological debate. His dedicated efforts to revitalize Christian piety through conversation and friendship made him a significant figure during the Catholic Counter-Reformation.
