This piece takes its inspiration from Romans 12:21: “Do not be overcome by evil, but overcome evil with good.” It was written to commemorate the martyrdom of six Jesuit priests and two women on the campus of Universidad Centroamericana (UCA) in El Salvador in 1989. It may be sung entirely in Spanish or English, or by alternating the two languages. The music moves through a sense of lament and ends with a gentle proclamation of the victory of good over evil.

The piece, of course, works with piano alone, as the JW Pepper site illustrates.
