In Genesis 3:31 we read "And the Lord God made for Adam and for his wife garments of skins, and clothed them." This implies the (sacrificial ?) killing of an animal for making the garments of skin.
I recently read the following:
"This is the first sacrifice in the long trajectory of bloody sacrifices that reaches all the way down to the coming of Jesus.....In Genesis 3:21 the death of an animal to cover the man and the woman is a picture of what is to come, the first step of an entire institution of sacrifices that points us finally to the supreme sacrifice and what Jesus did to take away our sin and cover up our shame.”

I checked "
Commentary on Genesis" by St. Ephrem the Syrian. On page 121 it says:
Why would beasts have been killed in their presence? Perhaps, it was so that by the animal's flesh Adam and Even might nourish their own persons, and that with the skins they might cover their nakedness, and also so that by the death of the animal Adam and Even might see the death of their own bodies.
There is no mention about this killing of the animal being a sacrifice or a foreshadow of the sacrifice of Christ.
Are there any quotes from the fathers about this? Does any of the fathers teach us that the killing of an animal for its skin to cover the nakedness of Adam was a foreshadow of the 'sacrifice' of Christ ?
