Your emphasis on the word "in" suggests that the Magisterium is the Deposit of Faith? Or the actual "teachings" from the Popes?
We discussed this earlier in the thread, but we never ventured any further than our agreement that the Magisterium (no matter the adjective placed in front of the word) is, indeed, infallible.
Just looking for some clarity...
I emphasized the word "in" to designate two things that Pope Pius IX said.
1) He said: "all those things are to be believed which are contained.... in her ordinary and universal magisterium." He previously, in that sentence, tells us exactly what it is we are to believe, which binds us, and where those things are to be found - in both the ordinary and universal magisterium.
Those things which we are bound to believe are "contained in" (vs the NO idea of "taught by"):
A) Scripture
B) Tradition
C) Solemn judgements (ex cathedra pronouncements)
D) Ordinary teachings of the Church's Universal Magisterium - which, quoting Pope Pius IX,
I already enunciated.
2) To attempt to correct Lad by demonstrating what the Magisterium actually is as explained according to Blessed Pope Pius IX and also Sheeben, so that he might actually cease promoting his vague and NO inspired ideas of what it is, in place of what it actually is.
