Paul Hoffer all over the map

Paul Hoffer has been doing yeoman's work in a recent thread about whether Mary sinned in "anxiously" looking for the boy Jesus in Jerusalem, in Luke 2.  He is an attorney, so we'd hope that he'd be versed in the art of consistent argumentation.  Unfortunately, if these comments are any indication, he's among the 99% of attorneys that give the other 1% a bad name...

Let's start, though, in the middle of Paul Hoffer's first comment to me, where he said something very interesting:

can you point me to the official binding Calvinist interpretative authority that interprets Scripture to mean what you think it does?

Unfortunately for PH, this question is meaningless and has been dealt with dozens of times on this blog alone.
So let's ask PH:  Can you point me to the official binding Magisterial interpretative authority that interprets Scripture to mean what you think it does? 
Let's see how many times he does so.  Or does he just give us a bunch of personal, private, fallible interpretations of biblical passages and "Magisterial documents", and does he ever give us an infallible means of knowing whether these "Magisterial" statements are infallible?  Let's find out.



Apologetics is the responsibility of all Christians.

How does he know that?  Did the Mag infallibly state such? If he appeals to a verse like 1 Peter 3:15, can he give an infallible Mag interp of it?
If not, how does he know any of this?



The Magisterium is only an office within the Church that has limited parameters and specific responsibilities.

How does he know that?  Did the Mag infallibly state such?
How does he know the Mag won't in the future correct him?



Or are there times when one only needs a mechanic or could roll up one’s sleeves and change the oil himself.

Bad analogy.  What I hear from RCs all the time is that I need infallibility to be sure of things theological, that as a fallible individual, I have no hope to escape the chaotic quagmire of Protestantism.  But when convenient, apparently PH doesn't tow that line.


I certainly can repeat what the Magisterium does teach

How does PH know that?  Did the Mag infallibly state such?
