Meilaender lays out his discussion of Christian Ethics, starting with an overview of what it means to be a human being, and specifically a Christian human being, wrestling with the nature of free will over and against inherited sin and imputed righteousness. He then lays out his central argument of the basis of Christian ethics in his chapters on Moral Theory and Moral Knowledge. The remaining chapters then explore and apply these ideas in particular situations in the Christian life.
Overall, Meilaender provides a helpful, if dense, discussion of Christian ethics and the unique tension in which Christians find themselves between sinner and saint, free and constrained, the flesh and the spirit. If his answers tend a little more towards the stoic and other-worldly than I think appropriate, that does not detract from the valuable discussion Meilaender provides.
My only real complaint is that Meilaender does not provide his readers with much help in following along with the argument. Both the individual chapters and the book as a whole could have benefited from clearer signposts--moments of summary, concluding statements, and more transparent transitions.
