Comment: You are getting back into validity vs. legitimacy.  He is breaking his promise of obedience (unless he does not bother asking) but is not doing something objectively evil, so it is not an immoral act.  God did not call it an abomination, the Rabbis of Babylon did.  The priest has the same level of spiritual authority as those who wrote Leviticus and signed Moses' name to it, more in fact because they can celebrate Eucharist.  Quit confusing authority with reality.
