Preface to the Fifth Edition

THE aim of this work was to state the Moral Theology of the Catholic Church as clearly and briefly as possible. A large portion of the Moral Theology of the Catholic Church depends on positive law. Many changes of far-reaching consequence were made in the positive law of the Church by the new Code of Canon Law. The new Code canonizes the law of the country on such important questions as Prescription and Contract. It changes the nature of more than one diriment impediment of Marriage. It alters numberless details on many other points of Church law. In this edition I have tried to bring my book into harmony with the existing law and teaching of the Catholic Church. T.
