We are joined on today's show by David Silversides, Minister of Loughbrickland Reformed Presbyterian Church of Ireland, and by Kenneth Stewart, Minister of Glasgow Reformed Presbyterian Church of Scotland. What is the place of the book of Psalms in the worship of God? Can hymns written by men, outside of the inspired Psalter, be used in the worship of God? What is the Regulative Principle of Worship? What is Exclusive Psalmody? Is it Biblical? What was the practice of the early church in regards to this issue? What was the view of many of the Reformers on this issue? Does Exclusive Psalmody promote or hinder the unity of the church? Can musical instruments be lawfully used in the worship of God?
