(2) Ambigua (ambiguous), captiosa (captious), male sonans (evil-sounding), piarum aurium offensiva (offensive to pious ears), etc.
A proposition is ambiguous when it is worded so as to present two or more senses, one of which is objectionable; captious when acceptable words are made to express objectionable thoughts; evil-sounding when improper words are used to express otherwise acceptable truths; offensive when verbal expression is such as rightly to shock the Catholic sense and delicacy of faith.
I think a lot of what we hear from theologians and even the hierarchy could be considered “ambiguous” or “captious.”
On the other hand, being overly concerned about “offensive to pious ears” leads us to mealymouthed mumbling instead of naming things, especially evil, by the right names. I’m all for keeping things clean, but you can’t explain (for example) what’s wrong with the concept of “gay marriage” without going into some pretty gruesome detail about what goes on between people afflicted with same-sex attraction disorders.
