It is not "Rome", but the Holy Spirit that decides. And, like Scripture, communicates that through chosen persons.
It is hypocrisy to accept the actions of the Church and the Holy Spirit when it is found flattering and then to reject it when it challenges you authoritative comfort zone.
That is an absurd statement, the logic of which would once again nuke the church if consistently followed.
For what Scripture reveals is that being an instrument of the Holy Spirit does not equate to assured infallibility, which is what Rome claims she has, for if it did then everyone in the first century would have had to submit to the Jews and their magisterium, and men like Caiaphas.
The issue here is not whether Rome can speak infallible truth, which even a donkey might, but that of the assured formulaic infallibility of Rome, in which she has "infallibly" declared that she was, is and ever will be infallible whenever she has spoken or will speak in accordance with her infallibly defined scope and subject-based criteria. Which renders her declaration of infallibility to be infallible and whatever else she utters under that premise in maintaining her "authoritative comfort zone."
Furthermore, our historically commonly held affirmation of core truths such as the deity of Christ does not rest upon Rome, but on the weight of Scripture, it alone having assured veracity.
And, like true men of God, the Divine writings were progressively established as being of God based upon its Heavenly qualities and Divine attestation, and not by men presuming authority over them.
And thus the church began in dissent from those who could lay claim to historical authority, as the authority of the former and its Object of faith rested upon Scripture and the attestive qualities and power of God it affirms. (Ps. 19: 7-11; 119; Mt. 22:29-45; Lk. 24:27,44; Jn. 5:39,42; Lk. 24:27,44; Jn. 5:36,39; Acts 2:14-35; 4:33; 5:12; 15:6-21;17:2,11; 18:28; 28:23; Rm. 15:19; 2Cor. 6:1-10; 12:12; Heb. 1-5-2:4, etc.)
"For the kingdom of God is not in word [proclamation], but in power. " (1 Corinthians 4:20) And most principally the Biblical gospel of grace with its manifest transformative regeneration (which multitudes of paedobaptized souls later realized upon true conversion) is "the power of God unto salvation." (Rm. 1:16) Thanks be to God!
Who just happen to be in Rome.
How convenient.
Any self-declared and self-authorized group which claims to be the mouthpiece of God in the earth that all others are bound to follow on pain of eternal damnation, is immediately suspect.
It doesn't matter one iota who they claim to be, what their pedigree is, or how long they've been around, claims like that smack of serious control and manipulation issues.
