Seems to me that a bigoted interpretation is the problem
Do not be fooled by the specious polemics posted by the Catholic apologists, who has blocked me after his arguments were refuted, but continues with the same. He imagines and argues that NT books not being called Scripture within the NT, and a lack of a table of contents of Scriptural books in Scripture negates SS, as if SS means Scripture must formally explicitly provide all things. And thus he argues for an alternative, that of an infallible church (in his case the Eastern one) to surely tell us what Scripture consists of and means (though significantly at odds with the Western "one true church" and its slightly different canon, as well as other cultic claimants to being the one true church) .
Yet as he has been told, the fact is that OT writings (which were foundational for the NT church) testify to souls correctly discerning and holding as authoritative certain men (prophets) and writings as being of God, even if opposed to the powers that be. And thus if believers could discern and hold such as authoritative, then they could do so with men like John the baptizer and other itinerant preachers who established their truth claims upon Scriptural substantiation in word and in power. And likewise additional writings in conflation with and complimentary to what had previously been established were recognized as being of God.
Thus consistent with this precedent and principle Scripture materially provides for the development of a canon, as well as for enjoining obedience to the oral preaching of Scriptural Truths, though even Catholicism does not presume that its declarations are spoken under inspiration of the Holy Spirit as with Scripture, nor consist of new public revelation, both of which men as the apostles preached, yet where subject to examination by Scripture.
As for the the problem of variant interpretations, this is not a new problem, and is one that was an issue in the founding of the church, and after it, of which i shall speak. But first note again that the Catholic premise and solution is that an infallible church is necessary to resolve such, as it alone can assuredly determine what Scripture and the word of God consists of and means, and thereby they can declare that, as the historical magisterial church, they are the one true church (again, in competition with other claimants to that title) which can authoritatively declare such extraScriptural and contrary teachings as
prayer to created beings in Heaven.
Thus all who dissent from her are in rebellion to God.
However, the idea of ensured perpetual magisterial infallibility is a novel one, unseen and unnecessary in Scripture, contrary to how the NT church began. Which, as said, was actually began in dissent from those who sat in the seat of Moses over Israel, (Mt. 23:2) who were the historical instruments and stewards of Scripture, (Rm. 3:2;9:4) and of Divine guidance, presence and perpetuation as they believed, (Gn. 12:2,3; 17:4,7,8; Ex. 19:5; Lv. 10:11; Dt. 4:31; 17:8-13; Ps, 11:4,9; Is. 41:10, Ps. 89:33,34; Jer. 7:23)
And instead they followed itinerant preachers whom the magisterium rejected, and whom they reproved by Scripture as being supreme, (Mk. 7:2-16) and established His Truth claims upon scriptural substantiation in word and in power. (Mt. 22:23-45; 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. 12:12, etc.)
Therefore unity of the NT church was not based upon the premise of ensured magisterial infallibility, or ecclesiastical veracity, but rested upon scriptural substantiation. And the unity of the NT was under clearly manifest men of God, while the so-called apostolic successors of Catholicism fail of both the qualifications and credentials of these Biblical apostles. (Acts 1:21,22; 1Cor. 9:1; Gal. 1:11,12; 2Cor. 6:1-0; 12:12)
True SS Prots look for men such as Peter and Paul, which certainly are contrary to the
deformation of the NT church.
But while the Catholic leadership is contrary to the NT church (in which is pastors were
never ever even titled "priests" except as being part of the general priesthood of all believers), yet a central magisterium is the Scriptural ideal, not as possessing ensured infallibility as per Rome in particular, but as in Scripture, having judicial authority, but being subject to examination by Scripture, with the possibility of just dissent.
It is this which Catholicism, as with cults, seeks to disallow, and with the veracity of their judgments resting upon Scriptural substantiation, but this is how the church began.
Meanwhile, the problem of different interpretations exists both under the Catholic model for determining the veracity of teaching as well as under Scripture being the supreme standard, yet while your Cath. opponent resorts to defining SS Protestantism as including Unitarians, Scientologists, Swedenborgians and Episcopalian, it remains that belief consists of what one does and effects, and those who hold most strongly to Scripture as the wholly inspired accurate word of God testify and evidence
greater unity in basic values and beliefs then the overall fruit of Catholicism.
