Why does the RC Denomination so passionately Reject and Protest this practice?
The RC Denomination so foundationally and passionately protests the Rule of Scripture in norming not because it rejects Scripture or has an alternative rule that is MORE inerrant, MORE inspired by God, MORE the inscripturated words of God, MORE reliable, MORE objectively knowable, MORE unalterable, MORE ecumenically embraced as authoriative, MORE above and beyond and outside all disputing parties. Rather the rejection is because the individual RC Denomination rejects accountability (and thus norming and any norm in such) in the sole, singular, exclusive, particular, unique, individual case of it itself alone, uniquely, individually.
From The Handbook of the Catholic Faith (page 151), "When the Catholic is asked for the substantiation for his belief, the correct answer is: From the teaching authority. This authority consists of the bishops of The Catholic Church in connection with the Pope in Rome. The faithful are thus freed from the typically Protestant question of 'is it true' and instead rests in quiet confidence that whatever the Catholic Church teaches is the teaching of Jesus Himself since Jesus said, 'whoever hears you hears me'." The Catholic Church itself says in the Catechism of itself (#87): Mindful of Christ's words to his apostles: “He who hears you, hears me”, The faithful receive with docility the teachings and directives that their pastors give them in different forms."
Since it itself declares that it itself exclusively and individually and institutionally is unaccountable and that it itself is infallible (in formal doctrine, AT LEAST) and it itself insists that when it itself exclusively and current speaks therefore God must agree, it itself is exempt from the issue of truthfulness, then the entire issue of truth and responsibility (and thus norming and the embraced norma normans in such) is simply made entirely, completely, wholly irrelevant (for it itself, exclusively and individyually). Truth, accountability, responsibility are all just laid aside (in the singular, exclusive case of self uniquely) and in its place, in stead of that, in lieu of that, the RCC substitutes its call for all to just submit to the unmitigated, God-like power of it itself (as claimed by itself for itself, exclusively), the POWER it itself claims for it itself simply "trumping" all else.
