The purpose of this study is to investigate and compare the basic structures of Matthew's and Paul's ethics, rather than to deal in detail with their teaching on specific moral issues. Dr. Mohrlang discusses their perspectives under the five headings of 'law', reward and punishment, relationship to Christ and the role of grace,' 'love,' and 'inner forces,' and gives special attention to the question of ethical motivation. He shows that Matthew's characteristic emphases reflect a system based on law, with submission to authority as its essential orientation, whilst for Paul it is 'the central theological conviction of God's grace in Christ' that is determinative, and the basis of ethical action is existence in the Spirit, which is 'both a result of and response to that grace'.
