Augustine’s Expositions of the Psalms are a lifetime investment. There are five volumes (translated by Boulding, edited by Ramsey, Fiedrowicz) which might set you back $140. Sell some of the books you bought last year, then with the money you have got left over, buy
Jason Byassee Praise Seeking Understanding: Reading the Psalms With Augustine, of which a fair amount is available at Google Book
and
Brian Brock Singing the Ethos of God: On the Place of Christian Ethics in Scripture of which a certain amount is also available at Google Book
The only name in whose powers the Christian can hope is Christ, and that hope excludes any hope for the outcome of history other than the triumph of that name. the essential point for Christian ethics is that it must serve this church., the community waiting in hope for God’s action. The church must thus remain clear about its true threat, says Augustine: the turning away of God’s face.
