647. Is the whole of the law of God contained in the rule of love of the neighbour laid dawn by Jesus?
"That rule certainly contains all the duties of men to one another; but it is necessary to show them its various applications, or they will continue to neglect them, as they do at the present day. Besides, natural law embraces all the circumstances of life, and the rule you have cited is only a part of it. Men need precise directions; general precepts are too vague, and leave too many doors open to human interpretations."
