The Enarrationes in Psalmos are an important source for understanding the Augustinian theology of desire, linking it to his systematic theology and his pastoral practice. In this paper I illustrate by overviewing the expositions on Psalms 11 (12), 12 (13), 23 (24), and 26 (27). These Psalms teach us to love, trust, and seek God only, a failure to do which marks the Donatist schism. Augustine mingles ideas from pagan philosophy’s quest for eudaimonia or beata vita—the good, happy, and blessed life—with biblical ideas. We want a stable happiness, and we must pursue wisdom; we can find stability in the rock that is Christ, to follow whom is to pursue wisdom rightly. Our desires must be converted to God, the only complete and perfect good and the source of eternal happiness, whom we must single-mindedly pursue with prayer and faith. While we must desire the eschaton and look to no earthly satisfaction, earthly goods may be received as gifts from God. One thing we can learn from studying the Enarrationes is how closely connected are the ideas of right love, the right church, and the right end; all three go together in Augustine’s theology.
