A surgeon who selects a scalpel in the operating room rejects a scalpel with a minute spot of defilement on it as readily as one that was severely defiled, because even the smallest spot means the scalpel is defiled and cannot be used in surgery. The degree of defilement is inconsequential. The fact of defilement is what matters to the surgeon. A thing is sterile or defiled, clean or unclean. A person is holy or unholy. God is not concerned with degrees, only with the absolute.
