Nonsense If the magisterium were led by the Holy Spirit, it would not need a majority vote. Matter of fact, it would be unanimous ALL THE TIME.
The Holy Spirit indwells believers.
Additionally, that does not exclude Catholics from having their own personal interpretation of Scripture. Their choice, however, is to adopt the one of the Catholic church, so in the end, EVERYONE makes an individual decision of what to believe, which interpretation they have, whether they arrive at it themselves, of just take the whole prepackaged deal.
Nonsense. Who are you to dictate how the Holy Spirit must act?
