I’m familiar with the word and its definitions.
“principles of behaviour in accordance with standards of right and wrong”
Here, try Webster’s 1828’s version:
“According to the rules of the divine law. An action is not in strictness morally good, which does not proceed from good motives, or a principle of love and obedience to the divine law and to the lawgiver. Charity bestowed to gratify pride, or justice done by compulsion, cannot be morally good in the sight of God.”
