According to Ivan panin, the 66 books are the correct one. That means god can wait and change the books of the bible. Protestants hold the correct one. RCC holds an outdated one. Today there is a correct bible and an incorrect bible.God reserves the correct Canons for the authentication of Protestants.
As a result, the Jews can only keep a correct OT Canon but not both. The Catholics can only keep the correct NT Canon but not both. Well, only the Protestants are keeping both a correct NT Canon and a correct OT Canon.
