Influence of the Forensic Model of Justification in the Interpretation of Romans 4:5

Abstract

This study examines the influence of the forensic model of
justification on the interpretation of Romans 4:5 within Christian
theological traditions. Romans 4:5 has long served as a central text
in debates concerning the nature of justification, particularly
whether justification should be understood as a legal declaration of
righteousness or as a transformative process involving moral
renewal. The study investigates how the forensic interpretation,
especially articulated during the Protestant Reformation by Martin
Luther and John Calvin, has shaped exegetical and theological
understandings of the Pauline doctrine of justification. It also
engages alternative interpretations from Roman Catholic theology,
represented by Robert Bellarmine and the Council of Trent, as well
as contemporary scholarship associated with the New Perspective on
Paul, particularly James D. G. Dunn and N. T. Wright. Using the
grammatical-historical method, this research conducts lexical,
syntactical, contextual, and theological analysis of Romans 4:5
within its broader literary context in Romans 3–5. Particular
attention is given to key Greek terms such as dikaioō “justify,”
asebēs “ungodly,” logizomai “credit” or “impute,” and dikaiosynē
“righteousness.” The findings demonstrate that Paul presents
justification as a forensic act in which God declares the ungodly
righteous through faith apart from works. The repeated use of legal
and accounting terminology strongly supports the doctrine of
imputed righteousness rather than infused righteousness or prior
moral transformation. The study concludes that the forensic model
most adequately explains the language and theological argument of
Romans 4:5. Justification in Paul is therefore fundamentally a
gracious judicial act of God, grounded in faith and the righteousness
of Christ, rather than in human merit or works.
