Somehow, after singing the gracious expressive words of Holy Scripture, the hymns written by mortal man seemed hollow and empty and cheap and common---employing flowery words to say so little" (emphasis his). The lyrics of many of Armstrong's hymns are believed to have been developed based on rhymed psalters. Some of these psalters include the Book of Psalms for Singing (published by the Board of Education and Publication, Reformed Presbyterian Church of North America), the Psalter Hymnal (published by the Christian Reformed Church), and the Psalms of David in Metre (commonly referred to as the "Scottish Psalter"). Armstrong is also thought to have utilized psalm settings by John Milton and William Kethe. As of the mid-1990s, Ambassador University Music Department chair Ross F. Jutsum had a large volume of psalm paraphrases, which is said to have been a primary source for Dwight Armstrong's selection of psalm lyric settings. The first hymns composed by Armstrong carried a copyright of 1948. Some of these were revised and several more were published in 1952, with more being published in 1958. The final group of hymns were published c. 1972-1974. Dwight's wife, Karen, was heavily involved with all of the compositions, helping her husband set lyrics to the music. The editions of the hymnal produced by the Worldwide Church of God between 1972 and 1974 were produced under the editorial direction of Ambassador College Music Department Chair Lucy H. Martin and Ambassador College student John Zahody. The most recent hymnal produced by the Worldwide Church of God was printed in 1993, and included eighty-four of Armstrong's previously published hymns as well as many internationally well-known hymns such as Battle Hymn of the Republic. Following Dwight's death in 1984, Herbert announced that a new hymnal was in the works and was to include dozens of new hymns written by Dwight during the late 1970s and early 1980s. However, the editorial team that worked on the revised hymnal chose to include only previously-published hymns by Dwight, along with numerous other well-known hymns and hymns composed by several other members of the Worldwide Church of God, including Ambassador College Music Department Chairman Ross F. Jutsum. Dwight's daughter, Deborah L. Armstrong, retains the original, unpublished hymns in her father's own handwriting.
