The mind reels
With an emphasis on the word "exactly". Imagine the Holy Inquisitor's salivating glee, at the opportunity to utilize modern interrogation techniques to commit unending authorized torture on anyone and everyone, to verify if they buy into Catholicism wholeheartedly. Break out the catechisms, the canons, the councils, the encyclicals, ad infinitum ad nauseum....
"....If a Catholic rejects even one tenet of Church teaching then they are as a result declaring that the Church is not a holy institution and more importantly the Church’s belief in truth is wrong....Catholicism has a monopoly on the truth, it is not good enough to only believe in some of the Church’s teachings, we have to and are logically required to believe in all of the Church’s teachings."
