I prefer "Scientia potestas est", though I obviously do not know the specific circumstances you refer to.
However, my advice to you - based on past experience of questions involving Latin on AnswerBank - is to check with an expert whatever answers you get here, including mine! For example, if your local secondary school has a Classics Department or even just a solitary Latin teacher, try to get a response from him/her. An alternative is to approach a local Catholic priest.
If someone suggests an online translation site, I'd treat that with even more care than answers here. They are generally much too vague or even ridiculous, unless you are quite knowledgeable about the language in any case.
