A line of questioning to my brothers who hold to exclusive psalmody. How much flexibility is allowed in the pursuit of singing psalms in worship? 1. May we transform the psalm by setting it to rhyme and meter? 2. May we transform the psalm by only singing part of the psalm? Many of Calvin's psalms in the beautiful Genevan Psalter are only parts of psalms because the psalms are very long. 3. May we transform the psalm by making explicit Christological connections that are in the psalms so that we explicitly sing about Jesus in worship? Thanks for answering these questions. To lay my cards on the table... If we may transform psalms by setting them to rhyme and meter, only singing parts of psalms, and making Christological connections explicit, then what is the relevant difference between such a transformed psalm and one of Isaac Watts' or Charles Wesley's hymns?
