The debate regarding the meaning of πίστις Χριστοῦ in the Pauline epistles continues and is important because of its implications for theology. In the phrase there is a double ambiguity, which touches not only the significance of the genitive, but also the meaning of πίστις. A brief look at some key texts in Romans suggests that the phrase refers primarily to the faith/faithfulness of Christ, but that this is also something shared by those who are ‘in Christ’. Through Christ God has done what the law could not do, enabling men and women to become his children, and so share not only in Christ's faith but in what he is. The phrase thus represents the ‘delicate balance between human behaviour and divine grace’ that characterises Paul's soteriology.
