According to Klaus Haacker’s The Theology of Paul’s Letter to the Romans, the theology at the opening of Romans consists of in a nutshell: 1) Davidic christology, which is a crucial link between Holy Scriptures and the gospel, 2) a healing or saving performance of the gospel due to the outcome of God’s being ‘right’ in his actions, and 3) the right way of life being the way of faith.

The major concerns of Romans are: 1) proclamation of peace with God and on earth, 2) righteousness redefined, translated into a code of ethics for the church, 3) suffering and hope, and 4) mystery of Israel.
