Why Vocal Music Only?
The church of Christ uses only vocal music in its worship because this is the example left us in the teaching of the New Testament in respect to worship. In guiding and directing man, when God uses specific words to direct how or what we do or give, that specific noun or verb excludes and forbids anything except that which is specified. When God in Genesis 6:14 specified that “gopher wood” be used to build the ark that directive excluded all other timber. When the New Testament writers specified “singing” (Ephesians 5:19; Colossians 3:16; Romans 15;9; 1Corinthians 14:15; Hebrews 2:12) it excludes “playing”, “blowing”, “picking”, “beating”, etc. It must also be kept in mind that instrumental music was never introduced into New Testament worship to please God but to satisfy and provide entertainment to man.
