From Justi Andreasen:
ShareIt is true that Adam and Eve before the Fall were naked and not ashamed. But the old Christian writers did not think of them as bare in our poor modern way. They say man was clothed with glory. That is to say, there was a rightness in him which made outer covering unnecessary. The body was not a trouble because the soul was not yet at war with itself. St. Ephrem says they were surrounded by glory. One can say it more simply still: grace had not yet gone out of them.
As the serpent is called the most subtle of the beasts, it is the most "naked" and closest to nature. It belongs to the raw pull of undifferentiated matter, the current that drags everything back toward dust. The serpent is not evil because it is powerful. It is dangerous because it is uncovered by any purpose higher than itself. It has not been named and integrated by Adam.
So when Adam and Eve ate, they felt shame because something had been lost. Like the serpent, they were now uncovered, no longer clothed in higher purpose. They had broken the law and, with it, the purpose God had given them. And so they snatch fig leaves.
Then comes that strange and merciful thing. God makes them garments of skin. The world is hard now, and He clothes them for hardness. Leaves are for summer. They will not do outside Eden. Since then men have been making larger and larger versions of the same defense. Clothes, houses, laws, customs, walls, roofs, medicine: all these are ways by which fallen creatures make life possible in a fallen world. (Read more.)
