Reply Obj. 5: The theologian considers sin chiefly as an offense against God; and the moral philosopher, as something contrary to reason. Hence Augustine defines sin with reference to its being "contrary to the eternal law," more fittingly than with reference to its being contrary to reason; the more so, as the eternal law directs us in many things that surpass human reason, e.g. in matters of faith. ________________________
QUESTION 72
OF THE DISTINCTION OF SINS
(In Nine Articles)
We must now consider the distinction of sins or vices: under which head there are nine points of inquiry:
(1) Whether sins are distinguished specifically by their objects?
(2) Of the distinction between spiritual and carnal sins;
(3) Whether sins differ in reference to their causes?
(4) Whether they differ with respect to those who are sinned against?
(5) Whether sins differ in relation to the debt of punishment?
(6) Whether they differ in regard to omission and commission?
