Martin Luther did not appeal to novelty — he appealed to Augustine. Luther's doctrines of the bondage of the will, the gratuity of divine grace, and justification by faith found their patristic warrant in Augustine's anti-Pelagian writings. Rome also claimed Augustine. This created a genuine intra-Western dispute over who properly inherits the Western patristic tradition, and it shows that the Reformation was at its core a debate about how to read the Fathers. But Luther and Augustine were not simply identical. Augustine's theology of grace was embedded in his ecclesiology: the church, through her sacraments and episcopal authority, mediates the grace he describes. Luther dismantled that structure. He retained Augustine's soteriology while rejecting the institutional framework Augustine had assumed — making their agreement and their divergence equally important for understanding both the Reformation and the Catholic tradition.
What the primary sources show
"I openly confess that I should not wish Free-will to be granted me, even if it could be so, nor anything else to be left in my own hands, whereby I might endeavour something towards my own salvation." Luther uses Augustine's anti-Pelagian arguments to argue that human will, apart from grace, can do nothing toward salvation.
Augustine's late anti-Pelagian synthesis — grace is entirely divine, the will is bound, predestination is real — gave Luther his soteriology. But Augustine's commitment to the visible church as the community where grace operates was the point where Luther's path diverged.
