The natural law is a rational creature's participation in the eternal law
Step-by-step explanation:
According to the Summa Theologica, there are four types of law:
1. Eternal law:- The eternal law reminds us of the whole universe and the pre-existing God.
2. Natural law:- It is the rational creature's participation in the eternal law. It may be a share of the eternal reason or the inclination of it own proper act, but it definitely has the participation of eternal law.
3. Human law:- The determinations in certain matters by the human reason is called human law.
4. Divine law:- This law refers to the Special Revelation as said by God in the Old and New testament of The Holy Book, The Bible. This law was needed for few reasons.
