Put another way, if the natural law is nothing but our rational participation in God^ judgment about the human good expressed in the eternal law (ST I-II.91.2), if basic participation specifies our humanity {ST I-II.91.4.1), and if our perfection in being, and thus our participation in God’s judgment, can be more or less complete according to the measure of our virtue, then of course every act of virtue is in accord with the natural law.
