I’ll concede your point regarding individual interpretation if you can find your way to realizing that your magesterium is comprised of individuals. Neither Protestant nor Catholic doctrine in contradiction to scripture is of God. Just because individuals are admired, learned or even exalted does not mean that any interpretation of theirs in contradiction with the written word has any truth in it. It’s another gospel. Shun it.
The Magisterium speaks with one voice, that of the Paraclete.
