The same law requires every act to be referred to God's glory
Thesis XV. In the same way the law of nature requires the rational creature to direct all its actions to the glory of God. God's glory is the natural end of all things, for 'the Lord has made all things for himself', and 'of him, through him and to him are all things'. Paul's precept, 'Do all to the glory of God', therefore belongs to the law of nature.
So no act that the agent does not refer to the glory of God can be truly good and just, since the goodness of actions is to be measured chiefly by their lawful end (Proverbs 16:4; Romans 11:36; 1 Corinthians 10:31).

XV. Similiter eadem naturae lex postulat, ut creatura rationalis omnes suas actiones ad Dei gloriam dirigat: quandoquidem Dei gloria est naturalis rerum omnium finis: quoniam universa propter semetipsum operatus est Dominus. Et ex ipso, & per ipsum, & in ipsum sunt omnia. Adeoque ad naturae legem pertinet Pauli praeceptum, Omnia in Dei gloriam facite. Ac proinde nulla actio quam agens ad Dei gloriam non refert, revera bona & justa esse potest: cum actionum bonitas ex legitimo fine praecipue metienda sit. Prov. 16. 4. Rom. 11. 36. 1 Cor. 10. 31.
