"The essence of the Divine Decrees is not the language itself, but the authority that uses language as its medium. Those who master the Decrees have the authority, and the words are merely there to express that authority," Melifilia said while rolling dice, "Be it phonograph records or created written records, they are all just cold noise without the power of authority attached to them. Even if mortals heard them, they would just be learning a sentence of noise. Only those who have mastered the authority of the Decrees can choose to teach them to others."
"And then the person being taught would experience mental contamination?" Aiden asked, following by rolling his dice.
"Exactly, merely speaking the Decrees doesn't affect another individual's mind. It is only when you try to forcibly infuse the power of the Decrees into the other person that they will begin to interfere with that person's spirit."
