"Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another
in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord." Colossians 3:16
We have never met a Reformed Christian
who believed singing the Psalms of Scripture to be sinful,
but there are many who believe
singing uninspired hymns and praise music to be so.
For the sake of unity,
if someone believes we have the right to compose new worship music,
we would ask that they forego their liberty
for the sake of the weaker brethren.
