" The Lord, by the Pope and the hierarchy -- by the hierarchy subject to the Pope --- governs His Church in such a way that it is always secure in the possession and understanding of its tradition. On the truths of the catechism, on the celebration of the Holy Sacrifice and on the sacraments, on the fundamental structure of the hierarchy, on the states of life and the call to perfect love, let us say on all the major points of tradition, the Church is assisted in such way that any baptized Catholic having the faith clearly knows what he must hold. Thus the simple Christian who, consulting tradition on a major point known to all, would refuse to follow a priest, a bishop, an episcopal conference, or even a Pope who would ruin tradition on this point, would not, as some charge, be showing signs characteristic of private judgment or pride; for it is not pride or insubordination to discern what the tradition is on major points, or to refuse to betray them. Whatever may be the collegiality of bishops, for example, or the secretary of the Roman Congregation who uses subterfuge to arrange things so that Catholic priests end up celebrating the Mass without giving any mark of adoration, no exterior sign of faith in the sacred mysteries, every faithful Catholic knows that it is inadmissable to celebrate Mass making this display of non-faith. One who would refuse to go to such a Mass is not exercising private judgment; he is not a rebel. He is a faithful Catholic established in a tradition that comes from the Apostles and which non one in the Church can change. For no one in the Church, whatever the hierarchical rank, be it ever so high, no one has the power to change the Church or the Apostolic tradition.
On all major points, the Apostolic tradition is quite clear. There is no need to scrutinize it through a magnifying glass, nor to be a cardinal or a prefect of some Roman dicastery to know what is against it. It is enough to have been instructed by the catechism and the liturgy prior to the modernist corruption.
Too often, when it is a question of not cutting oneself off from Rome, the faithful and priests have been formed in the sense of a partly worldly fear in such a way that they feel panic-stricken, that they are shaken in their consciences and they no longer examine anything once the first passer-by accuses them of not being with Rome. A truly Christian formation, on the contrary, teaches us to be careful to be in union with Rome not in fear or without discernment, but in light and peace according to filial fear in the Faith.
For it must be said, first of all, that on the major points the tradition of the Church is established, certain, irreformable; then, that every Christian instructed in the rudiments of the Faith, knows them without hesitation; thirdly, that it is faith and not private interpretation which makes us discern them, just as it is obedience, piety and love, and not insubordination, which makes us uphold this tradition; fourthly, that the attempts of the hierarchy or the weaknesses of the Pope which would tend to upset this tradition or let this tradition be upset will one day be overturned, while Tradition will triumph."
