The accepted baseline for study of the Psalms is genre analysis. Beyond that baseline, however, several interpretive options are available. Most often critical scholars seek to locate a particular Psalm in the life setting of ancient Israel, very often in a liturgical context. But two other alternatives are popularly practiced. On the one hand, "canonical interpretation" of the Psalter seeks to show how the various Psalms in the book are strategically situated, so that the shape of the Psalter in its several subsections is itself a theological, interpretive statement. On the other hand, there is a long tradition of Christian reading of the Psalms that takes Christ as their speaker or subject.
The Judaizing Calvin is a historical investigation of that latter practice among the 16th-century Reformers.
