The objective of this short introduction to Christian ethics is to help the reader come to a clearer understanding of the Christian life in our age. For this reason Christianity is presented against the background and within the context of other present-day efforts to understand the meaning of life. Whether he likes it or not, man must make decisions. He cannot choose not to choose. He must find some principle that will enable him to live coherent life, an integrating principle that will determine his ethical code.
