It astounds me, given the over-whelming use of psalms as central to gathered worship in the first four centuries, the absolute importance given to psalmody for the first two centuries of the post-Reformation Reformed churches, and the fact that the Book of Psalms is the only hymn book which can claim to be universal in its acceptance by the whole of Christendom and utterly inspired in all of its statements – it astounds me, I say, that so few psalms are sung in our worship services. Moreover, often nothing seems to earn the scorn and derision of others more than the suggestion that more psalms should be sung in worship. Indeed, the last few years have seen a number of writers strike out against exclusive psalmody. Given that life is too short ot engage in pointless polemics, I am left wondering which parallel universe these guys come from, where the most pressing and dangerous worship issue is clear that people sing too much of the Bible in their services. How terrifying a prospect that would be! Imagine: people actually singing songs that express the full range of human emotion in their worship using words of which God has explicitly said, ‘These are mine!’ Back here on Planet Earth, however, there is generally precious little chance of overloading on sound theology in song in most evangelical churches as the Marcion invasion is pretty much total and unopposed in the sphere of worship.
