Recent scholarship has reflected upon the relationship between sensus fidelium and scripture, but the Old Testament appears marginalized in this undertaking. This essay argues that the church can learn from Israel's faith for the concept of sensus fidelium. It presents the ‘canonical approach’ as an exegetical tool to bring the church as a reading community into conversation with many generations of believers in Israel and its own tradition. Furthermore, it provides one example of how a contemporary interpretation of an Old Testament text might deepen the understanding of the infallibility of the whole church in relation to its failures and sins.
