Moral theology

Definition and stakes

M. Valentine Theoretical Ethics

As this is the fullest disclosure of the duty of man, in all his relations, to God, to his fellow-men, and to his own end, it is not surprising that for so many centuries,26 the treatment of morals was made simply a part of general theology, and merely distinguished as Moral Theology.

Charles J. Callan Moral Theology

Thus, far from being useful merely to confessors as a guide by which they may detect and distinguish mortal and venial sins and the higher and lower degrees of culpability, Moral Theology in its broader aspect should be of the greatest service likewise to the individual in forming his own habits and character, and in particular to those who have the guidance of others, whether in or out of the confessional, such as pastors, preachers, teachers, and the like.

Thomas Slater A manual of moral theology for English-speaking countries (1925)

It is the task of moral theology to frame rules for human conduct according to the teaching of the Catholic Church, to decide what actions are good and what bad according to the principles of the Christian faith.
3. The actions over which a man has control are in a special sense called human acts, because they are due to his free choice. That man has the power of free choice or free will, is clearly taught in Holy Scripture, and is a dogma of faith.
