If Catholics are right about the authority of the Magesterium, then non-Catholics do not have the authority to determine which doctrines are orthodox (i.e. "spot on") and which are heterodox. My point is that the issue of the authority of the Magesterium is fundamental to all the rest. They all stand or fall on this.

The point in listing that stuff is to illustrate that a church so far removed from the actual writings of those who absolutely had the power of the keys said church claims, simply cannot possess that power.

The argument you give here is a question-begging argument in that it assumes that the Catholic Church's interpretation is "so far removed" from the orthodox interpretation, rather than assuming that it is your own interpretation that is so far removed from the orthodox interpretation. If the Catholic bishops have Magesterial authority, then they are the ones who determine what is the orthodox interpretation, not you. That's why your argument is question-begging; it assumes what you are trying to prove, i.e. that Catholic bishops do not have the authority to determine the orthodox interpretation of Scripture.
