You seem to be making the same mistake as the Jews in expecting a mortal kingdom to be set up at the hands of a physical king. Our ways are not His ways as the fall of the Jews once showed.
Protestants
have to claim that the Church is "invisible" to try and maintain legitimacy as "the Church"--but this is biblically untenable, 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).
The governmental structure of the New Israel is related to the Divine and historic government that existed before it. Bishops/shepherds were common names given to Israel's tribal leadership. So also "elder" was a common office of leadership over Israel. There were the kings of the monarchy, and there were prime ministers in Israel, second in command only to the reigning monarch. In a word, Israel always had a divinely instituted government, and this government was re-constututed under the New Covenant King in the first century. In the granting of the "Keys" to Peter (Matt 16:18-19/Isa 22:15-25), the appointment of the new 12 patriarchs (Matt 19:28; 10:1-4; Rev 21:12-14), and the ordination of bishops/elders and deacons, Jesus re-created Israel under the terms and conditions of the New Covenant order. 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).
The establishment of the authorized bishopric can be traced throughout the New Testament scriptures, and is especially highlighted in Acts and the letters to the Bishops Titus and Timothy. The authorized government of New Israel is evidenced in Holy Scripture, and was maintained from Clement, Ignatius, Irenaeus and those that followed.
Quite simply,
God created a visible Church and who can deny it from scripture? Protestantism, on the other hand, is 20,000 or more denoms that teach a myriad of different things, do not recognize each other's authority or doctrines, do not work together, compete against each other, etc.etc. It seems impossible to me that anyone could claim protestantism as a legitimate form of the one true Church of scripture (or history).
The Church of scripture is one united ecclesial body (Eph 4:3-4; Eph 4:13-16; Jn 17:21; Mt 16:18) without schismatic divisions (1 Cor 12:25; Rom 16:17; 1 Cor 1:10;
Jude 1:19; Gal 5:20;
3 John 1:9-10), with one teaching for all the churches (Acts 15:22-23,25,28/Acts 16:4-5; 1 Tim 1:3; 1 Cor 1:10; Eph 4:5;
Jude 1:3), and one bishopric authorized of and by the apostles (
Titus 1:5) by the laying on of hands in ordination (Heb 6:2; 2 Tim 1:6; 1 Tim 4:14;
Titus 1:5), sharing ministers back and forth among all churches (1 Cor 16:3; Rom 16:1,3,9,21,23; Phil 2:19,25;
Titus 3:12), receiving one another in fellowship and in greeting (Rom 15:5-7; Rom 16:16; Col 4:10,12,14;
3 John 1:9-10), where excommunication removes individuals from this one body (Matt 18:17;
1 Corinthians 5:1-2,4-5), and which existed from St. Peter and the apostles unto today (Matt 16:18-19; Eph 3:21).
Protestantism, in Contrast, is an endless schism of divisions with multiple different teachings and authority structures, with no effective means of excommunication and no traceable Apostolic Lineage.
