Scriptural Plurality in the Writings of Thomas Aquinas: The Case of Psalm 67, 7

Thomas Aquinas makes occasional references to the coexistence of multiple versions of the Bible. In particular, Thomas was familiar with several versions of the Latin Psalter used in liturgical and scholarly contexts. This article examines Thomas’s references to Ps. 67, 7 as a test case for understanding the role of scriptural plurality in his biblical hermeneutics. Thomas associates this verse with the theme of unity within religious life, the relation of the Eucharist to ecclesial unity, and ecclesial unity in itself. Thomas’s citations of alternate versions of this verse often appear to be consciously chosen in accord with his exegetical purposes.
