Worship Song

What is the place of song in a Lord’s Day church worship service?

Under the teaching ministry of the church, Trinity and Christ centered scriptural poems set to arrangements of melody, harmony, and rhythm, supporting their theological meaning, are to be sung, but not confused or mixed with musical entertainment. See, Psalmody and Hymnody, Psalm 119:172, Ephesians 5:18-19, Colossians 3:16
