St. Jude Thaddeus, patron of the desperate, was an apostle of Jesus, who preached the Gospel in the East where he was martyred. Even today people still invoke him as a comforter, a friend, and a beacon of hope.
Power and wealth can turn a good and faithful man into a depraved creature who forsakes the Lord and all His righteousness.
