Justification as Declaration and Deification

Theological accounts of the way God justifies sinners often struggle to combine forensic or declarative ideas about justification with transformationist ones. Luther seems to have especially steep problems here, not because he fails to think of justification as transformation – indeed deification – but because his forensic claims seem to take back what he says about transformation. Yet in the end Luther shows how forensic and transformationist ideas of even the boldest sort can cohere. At one level the concept of justifying faith as union with Christ extra nos combines the two, but their deeper unity is trinitarian: it lies in the Father's eternal verdict on the work of his incarnate Son, whose death and resurrection win for us the coming of the Spirit.
