Text: Summa Theologiae, Project Gutenberg #17897, First Part of the Second Part (Prima Secundae), translated by the Fathers of the English Dominican Province. The First Part of the Second Part of the Summa in the English Dominican translation (first printed 1911 to 1925; second and revised edition from 1920). A sample check on 2026-11-09 against pre-1931 printings at the Internet Archive (first printings of 1915 and 1916 and the second and revised edition of the 1920s) found that the article text matches, with no 1947 introduction, synopsis, or index.

We must now consider each kind of precept of the Old Law: and (1) the moral precepts, (2) the ceremonial precepts, (3) the judicial precepts. Under the first head there are twelve points of inquiry:

(1) Whether all the moral precepts of the Old Law belong to the law of nature?

(2) Whether the moral precepts of the Old Law are about the acts of all the virtues?

(3) Whether all the moral precepts of the Old Law are reducible to the ten precepts of the decalogue?

(4) How the precepts of the decalogue are distinguished from one another?

(5) Their number;

(6) Their order;

(7) The manner in which they were given;

(8) Whether they are dispensable?

(9) Whether the mode of observing a virtue comes under the precept of the Law?

(10) Whether the mode of charity comes under the precept?

(11) The distinction of other moral precepts;

(12) Whether the moral precepts of the Old Law justified man?
