In the early years of the 16th century a young German monk by the name of Martin Luther came to believe that the shape of the established Church and its relationship to the State did not fit the needs of the world in which he was called to live and serve. He wrote a commentary to re-imagine faith and Church, based around the work of Paul and especially the Epistle to the Romans. In the early years of the 20th century a young Swiss pastor by the name of Karl Barth came to believe that the shape of the established Church and its relationship to the State did not fit the needs of the world in which he was called to live and serve. He wrote a commentary to re-imagine faith and Church, based around the work of Paul and especially the Epistle to the Romans. In the early years of the 21st century it is clear once more that the shape of the established Church and its relationship to the State no longer fits the needs of the world in which we are called to live and serve. It is time, once more, to re-imagine the role of faith, Church and its place in the public square, based around the work of Paul and especially the Epistle to the Romans. As Helmut Thielicke explained in his book How Modern Should Theology Be?: `The gospel must constantly be forwarded to a new address, because the recipient is repeatedly changing his place of residence...if the basic questions of life have shifted, then I must redirect the message of the gospel.'
