So are you saying that Catholics as soon as JXXIII was elected or shortly after were suppose to know that he was a bad and not to follow him? You are dreaming. No Catholic in his right mind back then would EVER rebel against JXXIII and the Holy SEE. They would have been thrown out immediately and rightly so. I was an eye witness to those days.
JXXIII was right after PXII. During his reign he was given the same respect as PXII and NOONE rejected his authority to teach and bind. Everything and I mean everything was rock solid in terms of the faith for the average laity up until that faithful year of 1969.
You are literally proposing that the laity are equipped to judge and parse the actions of the HOLY SEE on a continuous basis for 50 years in order to be saved!
No, I am not saying anything about JXXIII, nothing at all.
I am saying that there were a number of people, including priests and nuns who did not go along with the NO because they knew it wasn't right. Most did not understand what was going on exactly, but they knew that what was happening in the Church when the NO was in it's infancy was definitely wrong and rejected it. They did not need to know all the details, it was and is enough to know that it's wrong and on that account to stay away.
Good thing too because they were the pioneers who laid the foundation for keeping the faith when your Church turns against everything that's been sacred your whole llife. OTOH, where would the faith be today had they ate the poison along with the rest who ate it like candy?
