It depends on the law of the state where the events you referred to took place. The "clergy-penitent" privilege is recognized in many states, but not all. But the "clergy-penitent" privilege has nothing to do with what it is you seem to be interested in. A "privilege," in the legal sense, is a rule, the purpose of which is to exclude certain evidence from trial based upon notions of social policy (e.g., attorney-client privilege). It is not possible to "violate" a priviilege. However, the priest;s conduct could be actionable under under other theories pursuant to the law of the state where these events took place, so you should consult with an attorney licensed to practice in that state to determine your rights and the costs/benefits of bringing a legal action in response to this matter. Good luck to you!
