The things that make someone righteous or sinful are unrelated to the physical.
Let me ask you a question slightly modified. Is it the physical that makes someone sinful or sinless or is it their soul/spirit?
Matthew 15
10Jesus called the crowd to Him and said, “Listen and understand.
11A man is not defiled by what enters his mouth, but by what comes out of it.”
16“Do you still not understand?” Jesus asked.
17“Do you not yet realize that whatever enters the mouth goes into the stomach and then is eliminated?
18But the things that come out of the mouth come from the heart, and these things defile a man.
19For out of the heart come evil thoughts, murder, adultery, sexual immorality, theft, false testimony, and slander.
20These are what defile a man, but eating with unwashed hands does not defile him.”
