Lumen Fidei has a detailed biography of the new State Secretary of His Holiness Pope Francis, en ESPANOL.
N.B. Check out Sandro Magister's masterful article (in Italian) on the role of the Secretary of State and the perfect Secretary of State: the Spaniard Cardinal Rafael Merry del Val, the genius of a diplomat tapped by Pope Saint Pius X.
