G. K. Wallace affirmed that it is scriptural to use an aid in the worship, such as a tuning fork or a microphone, but that it was sinful to use a piano or other mechanical instruments of music during the same service. In contrast, Julian O. Hunt set forth a very unique position: that instrumental music is an aid to worship, and at the same time that instrumental music is commanded and therefore required to be used. He affirmed “that according to the New Testament the infallibly safe side is for Christians to use mechanical instruments of music in connection with praises offered to God” (p. 137).
G. K. Wallace was a well known evangelist in churches of Christ. He was an active debater, lecturer, evangelist, writer, and college teacher and official.
