Paul Tillich and the Concept of Justification in the Reformation

In the first part of the essay, we summarise the constitutive elements of the concept of justification in the Reformation. These elements are the iustitia Christi aliena, Jesus’ substitutionary atonement as historical basis, Calvin’s unio mystica cum Christo and Luther’s “happy exchange”, the concept of sola fide, the principle that “faith is not a merit” and the “true faith contains true knowledge as well”, the forensic context of justification, imputatio is not infusio, the sharp distinction between justification and sanctification, the truth of simul iustus et peccator, the justification as existential experience and the adoption of all believers. In the second part, we inquire how Paul Tillich, in his Systematic Theology, reinterprets the concept of justification compared to the classic authors of the Reformation. It will be shown that Tillich basically changes the cognitive content of justification. The essay does not address the historical development of the concept of justification from Luther to Tillich, but concentrates only on the comparison of Tillich and the theology of the Reformation.
