courage of one's convictions, to have the

To act in accordance with one’s beliefs. The term may have originated in France since at first it was stated as the courage of his opinions (le courage de son opinion); it so appears in John Morley’s biography of Diderot (1878). A 1989 political cartoonist put an amusing twist on it in criticizing President George H.W. Bush’s changing stand on abortion: “It’s nice to see he has the courage of his elections” (Wasserman, Boston Globe, Nov. 9, 1989). See also put one's money where one's mouth is.
