Who was Saint Robert Bellarmine?

This outstanding scholar and devoted servant God

defended the Apostolic See against the anti-clericals in Venice and against the political tenets of James I of England. He composed an exhaustive apologetic work against the prevailing heretics of his day. In the field of church-state relations, he took a position based on principles now regarded as fundamentally democratic - authority originates with God, but is vested in the people, who entrust it to fit rulers.
