Why Church Eras Are Not A New Covenant Doctrine

Bob Thiel is back once again, attempting to smear COG7 and the work they do as the dead Sardis era. That's pretty rich considering COG7 is growing in members while every single "true remnant" Armstrongist COG is dying a slow, agonizing death, splintered into hundreds of little groups.

Thiel’s argument only works if you first accept a 20th-century Armstrongist map of church history, then treat that map as if Jesus wrote it. Under the New Covenant, that map is not required, not implied, and not how the letters in Revelation actually function.

What Thiel is actually claiming

The article he wrote is not a neutral history of the Church of God (Seventh Day). It is an identity brief. The load-bearing claim is: Revelation 2–3 is a timetable of successive “eras.”
COG7 is the leftover “Sardis era”: a name that it lives, but it is dead.

Thiel's "proof" is that it rejects church-era historiography, does not treat the annual holy days as binding, is relatively preterist on much of Revelation, and is therefore unwatchful.

He therefore claims most of its hundreds of thousands of members are being “connected to error” and will be overtaken “as a thief.” Imagine that, an Armstrongist COG leader claiming others are "connected to error". Bob has not looked in his mirror lately.

He restated the same scheme as recently as 2025: Sardis dominant c. 1600–1933, “but some are still in it”; Philadelphia dominant c. 1933–1986, “but some few faithful are still in it.”

Notice the date that does all the work: 1933. That is not a date Jesus gave. It is the year Herbert Armstrong broke with the Church of God (Seventh Day). The “era” doctrine is then used to baptize that organizational split as prophecy.

Why church eras are not a New Covenant doctrine

1. The letters were written to seven living churches at the same time

John is told to send the same book to seven congregations on a known Roman mail circuit in western Asia Minor (Revelation 1:11). In the opening vision, Christ walks among seven lampstands at once (1:12–13, 20). The refrain at the end of every letter is not “hear what the Spirit says to your era.” It is:

He who has an ear, let him hear what the Spirit says to the churches.

That is contemporaneous and corporate, not sequential and exclusive. A historicist overlay can be imposed on the text. It is not read out of it. Even conservative commentators who like a broad historical application usually treat the letters as types of churches that can coexist, not as a franchise timeline with one “true” corporation per century.

Several letters assume Christ’s coming is relevant to that congregation (Revelation 2:25; 3:3, 11). That sits badly with a scheme in which Sardis “ended” in 1933 and Philadelphia “ended” in 1986.

2. The New Covenant does not run on “mantles” and era headquarters

Jeremiah 31 and Hebrews 8 describe the New Covenant this way: the law written on hearts, sins remembered no more, and “they shall all know me, from the least of them to the greatest.” The mediating structure is Christ, not a human apostle who assigns your congregation a Revelation nickname.

Paul’s church is one body with many members (1 Corinthians 12; Ephesians 4). It is not a relay race in which COG7 is dead because it did not accept British-Israelism, a 19-year time-cycle chart, and Armstrong’s 1933 restart. “Philadelphia” in Revelation 3 is a local church commended for keeping Christ’s word with little strength. It is not a trademark that passed from Eugene, Oregon, to Pasadena, then to Charlotte, then to Grover Beach.

Once you drop the era machine, Thiel’s central sentence collapses:

No other group throughout recent history fits Jesus’ description of the Sardis church more than CG7-D.

That is only “obvious” if you already decided that Revelation 3:1–6 is a dossier on Denver.

3. The scheme is self-serving and unstable

Armstrong borrowed a Protestant historicist habit (Scofield, Larkin, and others also sliced church history into seven ages) and then customized the dates so that his departure from COG7 became the Philadelphia dawn. Different historicists use different dates. That alone should warn you that you are looking at a homiletical grid, not an exegetical necessity.

Thiel himself cannot keep the scheme clean. He needs Sardis to be “over” so COG7 can be the dead church, and he needs Sardis remnants to still exist so he can keep scolding them in 2026. He needs Philadelphia to have been 1933–1986, and he needs a Philadelphian remnant that is, conveniently, his Continuing Church of God. Every other Armstrongist split does the same trick in the opposite direction. After 1986 the movement became a demolition derby of “we kept the mantle / you became Laodicean.”  That is not New Covenant discernment. It is succession politics with proof texts. Proof texting his the only way Armstrongism can exist.

Where the article itself goes wrong

Jesus seems to be warning Sardis to know its history, stop changing doctrine, and pay attention to prophecy

That is not what Revelation 3:1–6 says. Jesus says:

they have a reputation for life but are dead

wake up and strengthen what remains

their works are not complete

remember what they received and heard

hold fast and repent

if they will not watch, he will come as a thief

a few have not defiled their garments

Thiel translates that into: accept Armstrong’s church-history reconstruction, keep the holy days as Armstrong defined them, and adopt his futurist reading of Revelation 13 and 18. That is a massive smuggling operation. “Remember what you received and heard” in a first-century letter is not “restore the Radio Church of God package.” Then, and only then, will you be allowed to understand when it is time to flee to Petra, where those who make it there will be treated to 3 1/2 years of Thiel preaching.

Size as a weapon, then as a trophy

Thiel notes that COG7 once pointed to its size as evidence it was not Sardis, then replies that size only means it is connecting ~300,000 people to error.

COG7’s own current public figures are more modest and still large by Armstrongist-Church-of-God standards: about 14,000 members and 230+ congregations in the U.S. and Canada, and more than 200,000 affiliated through its International Ministerial Congress in 40+ countries.

Meanwhile, the old Worldwide Church of God shattered. The larger English-speaking Armstrongist bodies are now in the low tens of thousands at most; UCG’s recent attendance figures are in the neighborhood of 12–14,000. Thiel’s CCOG claims “thousands” worldwide and “fastest growing ex-WCG group,” heavily concentrated in Africa—claims that have been repeatedly contested on the ground.

Two things can be true at once: Institutional headcount is not the test of faithfulness.
A man who treats COG7’s size as proof of mass deception, while treating his own claimed growth as a fruit of Philadelphia, is not applying a consistent rule. He is keeping score.

Armstrongism did not “gloat into” a larger, more alive Philadelphia. It fragmented. COG7 did not vanish. That does not make Denver the one true church. It does make the 1933 “Sardis died / Philadelphia was born” story look like organizational mythology.

Holy days: disagreement is not “Sardis death”

Thiel spends a long stretch rebutting COG7’s seven reasons for not binding the annual festivals. Some of those rebuttals are fair as internal arguments among Sabbatarians (Genesis 1:14 and moed; 1 Corinthians 5:7–8; early Quartodeciman practice). Others are weaker:“Ceremonial” is not a magic word, but Colossians 2:16–17 really does call festival, new moon, and Sabbath a shadow, with the substance in Christ. That is a New Covenant text, not a “liberal slide.”

The agricultural setting is not a “red herring” if you claim the Leviticus 23 calendar is still legislated for Gentiles in Phoenix and Nairobi.

“The calendar can’t be reconstructed from Scripture alone” is a real problem if you are going to make festival observance a mark of the true church.

COG7’s historic stance is: Sabbath as creation/moral distinctive; annual feasts as old-covenant national liturgy fulfilled in Christ; Lord’s Supper / Passover retained. You can argue with that. You cannot pretend Jesus’ letter to Sardis is a voting guide on Leviticus 23. That is Armstrongism using Revelation as a club.

Prophecy: preterism is an error or a school; it is not the Sardis label

Thiel’s October 2025 follow-up is clearer than the older piece: he is angry that Robert Coulter and CG7-D read much of Revelation 13 and 18 as already played out in medieval church-state history. Fine—say you think they are wrong about the Beast. Many historic Protestants were partial preterists or historicists; many futurists disagree with Thiel’s specific Beast package too.

What he cannot do is equate “they do not watch for my prophetic sequence” with “they are the dead church of Revelation 3.” 1 Thessalonians 5 tells the brethren to stay awake. It does not create a Philadelphia office that alone knows the chart.

The Luther paragraph is a smear, not an argument

Whaid Rose praised Luther as a Reformation figure who recovered justification by faith. Thiel answers with Luther’s antisemitic tracts and concludes Rose is not among the “few names in Sardis who have not defiled their garments.”

That is guilt by historical association. You can reject Luther’s later viciousness—and should—without treating any appreciation of 1517 as “the ecumenical agenda” and proof of defilement. COG7 is not Lutheran. Citing Luther on sola fide is not the same as adopting the Diet of Worms as the church’s finest hour in every respect. Thiel needs the Protestant scare because his identity system requires COG7 to be a dying husk sliding toward Sunday and Christmas. Actual COG7 materials still call the Sabbath God’s will “from creation to Christ,” not an elective.

Drift happens in every tradition, including his. Using a magazine essay about Luther as Revelation 3 evidence is not exegesis.

“Fewer and fewer are likely to be true Christians”

That sentence is the tell. Once “true Christian” means “person who accepts our era chart, our holy days, and our prophecy,” the conclusion is guaranteed before the study starts. It is unfalsifiable gatekeeping.

The New Covenant alternative

If the New Covenant is in force now—and Hebrews says the first covenant is obsolete and vanishing—then the people of God are those in Christ, sealed by the Spirit, not those correctly tagged Sardis or Philadelphia.

There is one church, not seven successive true denominations.

Revelation 2–3 is a pastoral X-ray of attitudes that can exist in any congregation: lost first love, faithful suffering, compromise, dead reputation, little strength that keeps the word, lukewarm self-satisfaction.

You do not need a 1933 corporate reboot for God to have a people.

“Watch” means moral and eschatological wakefulness, not subscription to one splinter’s newspaper.

Armstrongism mocked COG7 as Sardis while claiming the open door of Philadelphia. Forty years after Armstrong’s death, the heirs of that claim are small, split, and still excommunicating one another over who holds the mantle. Thiel’s latest articles are the same move: keep the era mythology, keep COG7 in the villain slot, and treat disagreement on festivals and futurism as spiritual death.

He can argue doctrine with COG7 on Sabbath practice, festivals, and Revelation. Those are real debates. What he cannot honestly do is promote those debates into Jesus’ verdict on a first-century church in Asia Minor, then use that verdict to explain why his group is the last faithful remnant in human history. That is not the New Covenant. That is a 21st-century Armstrongite succession myth proof-texted into oblivion.
