“If we care about genre—and we should—then we have to grapple with the question: if God gave us a book of praise songs, who are we to add to them? [ed. Michael] Bushell points to exclusive Psalmody as the logical consequence of sola scriptura. Why? First because of the importance of the genre of Book of Psalms within the scope of the canonized Bible.”
