Westminster Confession, Chapter 1, Paragraph 6
6- The whole counsel of God concerning all things necessary for his own glory, man’s salvation, faith and life, is either expressly set down in Scripture, or by good and necessary consequence may be deduced from Scripture: unto which nothing at any time is to be added, whether by new revelations of the Spirit, or traditions of men. Nevertheless, we acknowledge the inward illumination of the Spirit of God to be necessary for the saving understanding of such things as are revealed in the Word: and that there are some circumstances concerning the worship of God, and government of the church, common to human actions and societies, which are to be ordered by the light of nature, and Christian prudence, according to the general rules of the Word, which are always to be observed.
It seems to me that our light of nature thinker can get out of adjustment. The confession uses as it’s scripture proof:
1 Corinthians 11:13–14 Judge for yourselves:is it proper for a wife to pray to God with her head uncovered? Does not nature itself teach you that if a man wears long hair it is a disgrace for him,
Does it seems self-evident to you (and our culture) that it is disgraceful and shameful for a man to have long hair? Paul statement presumes that all will agree with his understanding of the light of nature. And this leads me back to my first statement which suggests that our light of nature thinker can get out of adjustment. Why do you think that is?
