In the Philippines, it is part of the culture to eat blood of animal, like blood of pork or beef. It is called dinugoan, wherein pure animal blood is cooked and seasoned with salt and spices. But in the Old Testament it says in Deuteronomy 12:23
Only be sure that you do not eat the blood, for the blood is the life, and you shall not eat the life with the flesh. While in the New Testament it says in Matthew 15:11
it is not what goes into the mouth that defiles a person, but what comes out of the mouth; this defiles a person.”
Any idea about this?
