Could somebody explain to me in detail (or link me to somewhere that it is) what exactly Gods Natural Law is? Its something I’ve seen used a lot in arguments, but still something I can’t quite understand. Where does it come from (obviously God ultimatly)? And is it a strict set of laws? Does it have a biblical base?
The natural law or the natural moral law of God is based on a thing acting for which it what created and it acting within its nature. The natural law is NOT the same thing as the laws of nature like gravity or science; that is another completely different subject.
We as humans were created with a rational nature or rational soul, so that we can understand something beyond our senses alone Paul even says in Romans 2:15-16 where he says man knows good and evil as he has “the gospel written on there hearts” that they have a conscience and inherently know certain acts are wrong, like murder is wrong.
Animals on the other hand have what St. Thomas Aquinas calls sensitive souls,(not eternal souls) in that they act within their senses, we act outside (at times) of our strict senses because we are rational beings.
Food may look and smell appealing but we can rationalize that it is bad for us, so we stay away from it. My dog sees food as something that will fill her belly and doesn’t care if it is good for her or not.
Anyway, the primary reason we eat food is nurishment for the food gives us vitamins and sustanance to stay alive. There are secondary and tertiary effects of food too as it tastes good and smells good and I suppose looks good (I’m probably making some people hungry).
So, again the primary function of food being to nurish our bodies, Now if we eat and then go into the bathroom and throw it up then we have just acted in a dysfunctional manner as this is a dysfunction called bulimia an eating disorder because the primary function of that food is nurishment and to throw it up only frustrates its purpose.
And the marital act works the same way as food as its primary function is procreation to propgate the human race. However, secondary functions also apply as it feels good and unites us the couple together. But the primary function is procreation. However if we contracept, we then frustrate the primary function of God’s natural moral law and thus go against what God created us for and against His natural moral law.
