Headcovering, Will Hair Do?

In light of the previous teaching

1 Never the less, Unity is GOD's plan
-The man and the woman are not independent
-There should be dependence and unity between them

2 Is Hair a Head Covering?
-Nature
-Women's long hair is their natural covering and is a glory to them
-This shows that it is proper to wear a head covering in worship
-The head covering for worship is not long hair

v16 -The apostle is saying that there is no other practice among them or among the other Churches of GOD (that women should worship while uncovered)
