Ok, so clearly isa has no interest in honest dialogue. For Catholics, Natural Law is absolutely and necessarily tied to God. We don't subscribe to any other form of natura law. If Isa wants to play word games he is free to do so. I'm out. Responsibility issues.
Btw, the authority your CCC invokes on the existence of "Natural Law" didn't believe in God, certainly not the Christian One.
What is your point? Quoting a witness to the truth of the Natural Law, does not alter one bit, the Catholic position on the natural law. As St. Thomas Aquinas himself states,
"Wherefore, since all things subject to Divine providence
are ruled and measured by the eternal law, as was stated above (Article 1); it is evident that all things partake somewhat of the eternal law, in so far as, namely, from its being imprinted on them, they derive their respective inclinations to their proper acts and ends. Now among all others, the rational creature is subject to Divine providence
in the most excellent way, in so far as it partakes of a share of providence, by being provident both for itself and for others. Wherefore it has a share of the Eternal Reason, whereby it has a natural inclination to its proper act and end: and this participation of the eternal law in the rational creature is called the natural law. Hence the Psalmist after saying (Psalm 4:6): "Offer up the sacrifice of justice," as though someone asked what the works of justice are, adds: "Many say, Who showeth us good things?" in answer to which question he says: "The light of Thy countenance, O Lord, is signed upon us": thus implying that the light of natural reason, whereby we discern what is good and what is evil, which is the function of the natural law, is nothing else than an imprint on us of the Divine light
. It is therefore evident that the natural law is nothing else than the rational creature's participation of the eternal law." (ST, I-II, 91, 2).
Not sure why you think Catholic Natural Law Theory is not dependent on God. I think you just like to say that in order to make try to make Catholics look bad.
BTW, if it is unclear, the Eternal Law is God's provident plan for creation.
