Abstract
The article deals with Augustine’s soteriological ideas, with which he tries to fight against Donatism trying to reestablish Peace, underlining the importance of the dead of Christ as Redeemer, taking as point of departure the text of Psalm 21, 28-29, to demonstrate the universality of salvation against the Donatist’s concept of Redemption. The article underlines the main Soteriological and Ecclesiological ideas of St. Augustine, making the comparison between the text of Psalm 22 used by Augustine, the Text of the Vulgata and the one used by Cyprian within his Testimonia ad Quirinum. Finally the importance of Peace is underlined, focusing on the Elogium pacis that Augustine presents in the enarratio to Psalm 147.
