John Calvin paid particular attention to the Psalms, lecturing on them and giving prominence to them in his preaching, and publishing a commentary on the Psalter. His work is additionally interesting because this normally reticent reformer avowedly identifies himself with David, and so in his comments on the Psalter, for ‘David’ one may often read ‘John Calvin’. His commentary on the Psalms appeared in 1557, two years before the definitive edition of the Institutes. Herman Selderhuis provides a careful account of Calvin's doctrine of God (his locus de deo) drawn from this commentary. (Though in fact the author does not interpret this narrowly as there are discussions on Calvin's anthropology and ecclesiology and more besides.) He draws attention to the current scholarly tendency to go to Calvin's commentaries and sermons first, and to read his theological works in their light, an approach that he endorses. But his own account of what Calvin says about the Psalms suggests that doing this is not in fact very revealing; not a rich feast of new insights, but rather meagre fare. Calvin tends to give us the same themes, perhaps with different emphases, in each, but this conclusion (which perhaps the author would not himself wholly endorse) is itself not without importance, of course. One passage (though from Psalm xviii.8, not xviii.14 as stated [p. 288]) that Selderhuis quotes because it provides an insight into Calvin's spirituality, his fearfulness and yet his confidence in God, and the influence of the weather on his spirits, in fact has a parallel passage in Institutes 1.17.1. One puzzle is why Selderhuis has not paid more attention to Augustine of Hippo. (There are only four references in the index). Augustine, who also wrote in extenso on the Psalms, is Calvin's hero. Would not a comparison of the two have been additionally insightful? However, these qualifications should not detract from the central virtues of Selderhuis's work. Translated from the Dutch, it is a valuable addition to Texts and Studies in Reformation and Post-Reformation Thought, a series (with Richard Muller as its general editor) that is steadily growing in importance for Reformation scholarship.
