The use of Romans 5:12-21 almost exclusively in debates regarding the origin and universality of sin has resulted in the super valorization of the discussion on segment 12d, with fundamental aspects for the understanding of the theological message comprised in the Pauline text going almost unnoticed. One of the pretermitted aspects was the allusions to Isaiah 53:11-12. The present research aims to contribute to a perception of the effects these allusions produced on Paul s contemporaries. They make the hearers/readers picture the image of the Servant who by his knowledge will justify many, present in Isaiah s text, as well as the biblical-theological categories of the New Exodus and the New Creation comprised in its context and to which it is strongly interconnected. Following that, the recovery of the value of these allusions would enable a more adequate understanding of the hermeneutical, theological and rhetorical potential of the pericope, which would result in a true contribution for the theological debate, considering that Paul s pericope plays an important role in such debate. The methodology used in this study will be that proposed by G. K. Beale, which, by contemplating the synchronic and diachronic aspects of the research, proposes an exegetical and interpretative analysis, therefore proving itself perfectly adequate to enable the perception of Paul s intention when using Isaiah s text.
