Does not even nature itself teach you, that, if a man has long hair, it is a shame unto him?
All Commentaries on 1 Corinthians 11:14 Go To 1 Corinthians 11
Tertullian of Carthage
AD 220
If you demand a divine law, you have that common one prevailing all over the world, written on the tablets of nature, to which also St. Paul is accustomed to appeal. Thus he says concerning the veiling of women: “Does not nature teach you this?” Again, in saying in his letter to the Romans that the Gentiles do by nature what the law prescribes, he hints at the existence of natural law and a nature founded on law.
