This bull contradicts you in the very first paragraph:
The only-begotten Son of the Eternal Father, who came on earth to bring salvation and the light of divine wisdom to men, conferred a great and wonderful blessing on the world when, about to ascend again into heaven, He commanded the Apostles to go and teach all nations,(1) and left the Church which He had founded to be the common and supreme teacher of the peoples.
It is precisely this teaching Church (this is, the Magisterium) which Christ left, in order to be the common and supreme teacher of the peoples. The teaching Church is the Rule of Faith for all generations; contrary to what Mr. Drew says.
By the way, this bull also refers to the ecuмenical councils as the "flowers of ALL earthly wisdom".
Your above quote from Pope Leo XIII does not agree whatsoever with your echoing of V2's LG.
Yes, certainly the Church is the supreme teacher because the Church is Christ, it is Christ's mystical body which He established on earth in order to teach us how to get to heaven. He left us His Mystical Body, which IS the Church. The Church is most assuredly the supreme teacher.
Catholics, being members of the Church, are members of Christ's mystical Body, the Church. Christ and the Church are one. They are one and the same, which is the reason why the Church He left us can never err and will last till the end of time - because the Church is Christ.
Heaven and earth will pass away, but it is His Words that will last forever. When you read dogma, you read His Words. His words are contained the Solemn Magisterium as well as in both the Ordinary Magisterium and the Universal Magisterium. This is the teaching of V1.
OTOH, the NO church is a church where all the bishops of the world in union with pope, gather in council, or are dispersed throughout the world teach whatever they want - and on that account alone whatever they teach is binding and infallible. This is the NO church. This is a NO doctrine and does not agree with Pope Leo's or any other Church teaching.
Stubborn, how do you distinguish an infallible teaching?
"Wherefore, by divine and catholic faith all those things are to be believed, 1) which are contained in the word of God as found in scripture and tradition, and 2) which are proposed by the church as matters to be believed as divinely revealed, whether by her solemn judgment or in her ordinary and universal magisterium." - Pope Pius IX, First Vatican Council
Truth is "the matter", the way we learn this truth is via "the method". We Catholics are bound to truth, it is the truth that binds us. It is therefore the matter that binds us, not the method. It is therefore "the matter" which is our rule of faith, not "the method".
OTOH, within the NO church, it is the method that binds them, not the matter. The NO matter ever changing and is therefore impossible to bind oneself too. This is why within the NO, they are bound to the method, not the matter, i.e. they are bound to teachings of their popes and bishops which are lies, on that account they cannot be bound to truth. They are bound to the method, not the matter.
