How do you observe this law?

“And if any animal which you may eat dies, he who touches its carcass shall be unclean until evening.” (Lev. 11:39)

The fact is that the law of clean and unclean animals was given in this context:

"But I have said to you, ‘You shall inherit their land, and I will give it to you to possess, a land flowing with milk and honey.’ I am the Lord your God, who has separated you from the peoples.” (Lev. 20:24).

These laws are all in the context of the promise of the ancient land of Israel to the ancient people of the Jews.

The Church, the new covenant people of God, is no longer restricted to one physical piece of land and one ethnic group. Christians who follow the teachings of the apostles understand that, and so we are not in bondage to these ancient, decayed food laws.

If I raised food animals and I found one of them dead, I wouldn't touch it without having gloves on. You never know what might have killed it or what diseases it might have had.
