Red Monkey:

On uncleanness and sin: I understand why you ask the question and why you raise an objection. The question here is whether defiling is equal to sin or simply "desanctifies" (if I can coin a term). The term translated abominable in Leviticus means to do something horrible or detesting to the soul. So this act is offensive, and renders one cultically disqualified, but it is not as severe a category as sin. This is why a washing can suffice versus a sacrifice to restore cleanliness (Lev 11:24-25) and why its effect only lasts for a time. Hope this helps.
