Answer:
Attacked the liberal Christian theology that had embraced the idea of progress.
Step-by-step explanation:
Karl Barth, a Swiss theologian wrote an Epistle to the Romans based on the New Testament Book of Romans by Apostle Paul. His book is a way to restructure his thinking towards the Protestant belief of the way Christianity was projected by Paul. This attempt to restructure the theology of the Protestant belief system by Barth led to the address of the many dilemmas faced by the modern preachers in their teachings such as the saving grace of God and how to fully and correctly incorporate the power and image of God to the believers. He attacked the liberal theological approach of the Christians in their embrace of the idea of progress. Barth argues that the preachers of this day are facing the same problems that Paul faced during his time. Barth also focused on the critical interpretation of the book of the Romans, ad gave a co-relational connection of the Bible, religion and the theology that is in the past and even now.
