Abstract This article analyses Hispano-Mozarabic Eucharistic prayers in order to study the reception of Augustine’s theology. Especially, Augustine’s doctrine of the Trinity and his Christology were employed in the late 6th and 7th centuries to overcome Arianism . Thereby, several pivotal Augustinian formulations were dogmatised at the Councils of Toledo. These formulations were also adapted in the Hispano-Mozarabic Eucharistic prayers. Furthermore, these prayers also employ motifs and overarching concepts drawn from Augustine’s doctrine of grace. In this way, they emphasise the connection between sacramental theology and a theology of the cross. However, other aspects of Augustine’s soteriology, particularly his doctrine of predestination or his terminology of gracious grace, are largely neglected. Thus, these Eucharistic prayers contain a broad and condensed form of Augustine’s theology. This illustrates how a reciprocal relationship between the lex credendi and the lex orandi shaped the development of Augustinianism .
