Massah was the son of Benjamin Warner and Anna Louisa Stotz, and husband of Celestine Victoria Reinke, granddaughter of Moravian bishop Christian Gottlieb Hueffel (married March 30, 1869, Bethlehem, Pennsylvania).
He was a Moravian organist, composer, and hymnal editor.
In his youth, Warner served a year in Salem as apprentice to the printing trade, then took up the study of music, especially the piano.
He spent a year in Philadelphia, then three years in Leipzig, Germany, studying under Hans von Bülow and other German masters.
Returning to Philadelphia, Warner took up music as a profession. He played the organ at St. Luke’s Episcopal Church in Germantown, and later at the Woodland Presbyterian Church, where he served the rest of his life.
