C Preston Noel III, 46, has devoted his adult life to a Catholic-based cultural organization dedicated to what they call the core values of Christian civilization: Tradition, Family and Property. The organization, which started in Brazil in 1960 and came to the United States in 1974, makes its voice heard through street protests, postcard and e-mail campaigns and a sister lobbying organization in Washington. It counts about 100 full-time volunteers and several thousand donors. Noel, who was raised in St. Louis, works as Chicago coordinator and as a lobbyist and publication editor in Washington.
