Meaning the entire Bible, but which does not establish an assuredly infallible church as supreme over any Scripture, which preceded it, any more than it did for Israel, which came before any Scripture was written (first by Moses).
And which writings, like true men of God, were progressively established as being of God due to their Divine qualities and attestation in conformity to what was prior established as from God.
And which the positional powers that be were to recognize and confirm, but as Scripture testifies, often they did not, but which did not change who or what they were, while judging the error of those who sat in power. Thus the church began in dissent and often by such faith is preserved.
The issue is that both the instruments and stewards of Holy Writ are inferior to it, neither being wholly inspired of God in all such say, and as written, Scripture was the transcendent standard for obedience and testing truth claims, as is abundantly evidenced . And thus it was upon Scriptural substantiation in word and in power that the church was established as being of God, and further complementary and confirmatory writings were established as being of God.
Well ok.
Good luck with being a Jew. :)
