Protestants have to claim that the Church is "invisible" to try and maintain legitimacy as "the Church"--but this is biblically untenable
It is exactly how it worked in the NT.
Heb 11 shows a continuation from OT saints/church to NT saints church -
39 And all these, having gained approval through their faith, did not receive what was promised, 40 because God had provided something better for us, so that apart from us they would not be made perfect.
Rom 11 shows that continuation as saints in both OT and NT - grafted into the same tree
17 But if some of the branches were broken off, and you, being a wild olive, were grafted in among them and became partaker with them of the rich root of the olive tree, 18 do not be arrogant toward the branches; but if you are arrogant, remember that it is not you who supports the root, but the root supports you. 19 You will say then, “Branches were broken off so that I might be grafted in.” 20 Quite right, they were broken off for their unbelief, but you stand by your faith. Do not be conceited, but fear; 21 for if God did not spare the natural branches, He will not spare you, either.
This is not because a duly elected High Priest of the OT appointed Christ, or appointed Paul or Appointed the 12. No -- rather it is a continuation "of the faith" - pure faith regardless of the apostasy of the high priest at the time of Christ.
As we see in
Romans 9
6 But it is not as though the word of God has failed. For they are not all Israel who are descended from Israel; 7 nor are they all children because they are Abraham’s descendants, but: “through Isaac your descendants shall be named.” 8 That is, it is not the children of the flesh who are children of God, but the children of the promise are regarded as descendants.
, for the Church of the Holy Scriptures is not invisible but consists of a clear apostolic succession of ordained bishops that hold authority by virtue of their apostolic office (a calling that individuals may or may not live up to, as Judas demonstrated).
Just like the One True Nation Church started by God at Sinai had God appointed priests with a divinely ordained succession of priests... still existing at the time of Christ.
Take a gooood look at the New Covenant in Jer 31:31-34 -- AND ALSO -- in Heb 8:6-12 ... unchanged... verbatim the same.
Jer 31 (and also Heb 8)
31 “Behold, days are coming,” declares the Lord, “when I will make a new covenant with the
house of Israel and the
house of Judah, 32 not like the covenant which I made with their fathers on the day I took them by the hand to bring them out of the land of Egypt, My covenant which they broke, although I was a husband to them,” declares the Lord. 33 “For this is the covenant which I will make with
the house of Israel after those days,” declares the Lord: “I will put My law within them and write it on their heart; and I will be their God, and they shall be My people. 34 They will not teach again, each one his neighbor and each one his brother, saying, ‘Know the Lord,’ for they will all know Me, from the least of them to the greatest of them,” declares the Lord, “for I will forgive their wrongdoing, and their sin I will no longer remember.”
Rom 2:28 For he is
not a Jew who is one outwardly, nor is circumcision that
which is outward in the flesh. 29 But
he is a Jew who is one inwardly; and circumcision is of the heart, by the Spirit, not by the letter; and his praise is not from people, but from God.
Christ re-instituted the familiar leadership offices from Israel's history, and established the Twelve who expanded the Bishopric/Episcopate for New Israel. They went about ordaining men to offices in every city by the laying on of hands, and commissioned those appointees to continue this same practice also by the laying on of hands (a cardinal NT doctrine according to
Hebrews 6:1-2).
And they predicted that apostasy would arise within the group.
Acts 20:
27 For I did not shrink from declaring to you the whole purpose of God. 28 Be on guard for yourselves and for all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood. 29 I know that
after my departure savage wolves will come in among you, not sparing the flock; 30 and
from among your own selves men will arise, speaking perverse things to draw away the disciples after them. 31 Therefore, be on the alert, remembering that night and day for a period of three years I did not cease to admonish each one with tears.
2 Thess 2: A great apostasy takes place before Christ's return according to the Apostles
Now we ask you, brothers
and sisters, regarding the coming of our Lord Jesus Christ and our gathering together to Him, 2 that you not be quickly shaken from your composure or be disturbed either by a spirit, or a message, or a letter as if from us, to the effect that the day of the Lord has come. 3 No one is to deceive you in any way! For
it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction
2 Cor 11:12 But what I am doing I will also
continue to do, so that I may eliminate the opportunity from those
who want an opportunity to be regarded just as we are in the matter about which they are boasting. 13 For such men
are false apostles, deceitful workers, disguising themselves as apostles of Christ. 14 No wonder, for even Satan disguises himself as an angel of light. 15 Therefore it is not surprising if his
servants also disguise themselves as servants of righteousness, whose end will be according to their deeds.
So that sort of apostasy from within feature - is in fact a reality even in the first century.
1 Tim 1:3 Just as I urged you upon my departure for Macedonia, to
remain on at Ephesus so that you would instruct certain people not to teach strange doctrines, 4 nor to pay attention to myths and endless genealogies, which give rise to useless speculation rather than
advance the plan of God, which is by faith,
so I urge you now.
The apostasy began taking root in the first century - according to the Apostle John
3 John 1:10 For this reason, if I come, I will call attention to his deeds which he does,
unjustly accusing us with malicious words; and not satisfied with this, he himself does not receive the brothers either, and
he forbids those who want to do so and puts them out of the church.
