"I appeal to you, brethren, by the name of our Lord Jesus Christ, that all of you agree and that there be no dissensions among you, but that you be united in the same mind and the same judgment" (1 Cor. 1:10).
This does not speak to the visible structure of the Church as such, but it is helpful in demonstrating the unity of the Church
which presupposes an institutional character. The Protestant notion of a loose confederation of communities who "agree on essentials", where there is "unity in disunity", is incompatible with Paul's teaching that Christians be united in one mind and one judgment, a unity which, as we have seen from John 17, our Lord says is nothing other than the unity of the Trinity.
That kind of unity in judgment presupposes a single institutional framework. Yes, the Church is one Body with many members and diverse gifts, but Paul never says they are to have diverse
beliefs or diverse
judgments.
The Bible repeatedly teaches that the Church is indefectible; therefore, the hypothetical of rejecting the (one true, historic) Church, as supposedly going against the Bible,
is impossible according to the Bible. It is not a situation that would ever come up, because of God’s promised protection.
What the Bible says is to reject those who cause divisions, which is the very essence of the onset of Protestantism: schism, sectarianism, and division. It is Protestantism that departed from the historic Church, which is indefectible and infallible (see also 1 Tim 3:15).
This is why we reject any form of Protestantism, because all fail the test of allegiance to God’s Word in Holy Scripture, and the historical pedigree that the fathers always taught was necessary.
Every heretic in the history of the world thumbed their nose at the institutional Church and went by Scripture alone. It is the heretical worldview to do so, precisely because they know they can’t prove that their views were passed down through history in an unbroken succession.
Therefore, heresies and Protestantism either had to play games with history in order to pretend that it fits with their views, or ignore it altogether.
Of course, all authority ultimately comes from God (Paul was called before he was born: Gal 1:15). It is the pitting of the ultimate source against the secondary, human source (the Church) which is the problem in your approach and that of Protestantism in general. You guys don’t like human, institutional authority and don’t have enough faith to believe that God can and does preserve it, so you try to undermine it by fallacious arguments, as presently.
No doubt you aren’t even aware that you are doing it. To do this is automatic in Protestantism; it’s like breathing. It’s like the fish that doesn’t know it’s in water. It all comes from the rejection of the infallibility of the Church (which is one thing that
sola Scriptura always entails).
In Galatians 1-2 Paul is referring to his initial conversion. But even then God made sure there was someone else around, to urge him to get baptized (Ananias: Acts 22:12-16). He received the revelation initially and then sought to have it confirmed by Church authority (Gal 2:1-2); then his authority was accepted or verified by James, Peter, and John (Gal 2:9). So we see that the Bible doesn’t pit the divine call directly from God, against Church authority, as you do.
You do it because it is Protestant man-made tradition to do so; period, and because the Protestant has to always undermine the authority of the Church, and the Catholic Church, in order to bolster his own anti-system, that was set up against the historic Church in the first place.
