Question 5
Bercot challenges the idea that evangelical Christianity is basically unchanged for 1,900 years while also claiming “orthodox Christianity” changed radically within 50 years after the apostles; what assumptions about church history have to be true for both claims to coexist, and do those assumptions actually hold up?
Another way to ask: Bercot questions how evangelicals can say their faith stayed the same for 1,900 years but also say the church changed fast right after the apostles. What would have to be true about history for both claims to be right, and do you think it really is true?

Direct Answer For both claims to coexist, you would have to assume massive, rapid corruption happened immediately after the apostles, yet somehow modern evangelical beliefs later preserved the apostolic pattern essentially unchanged for 1,900 years; Bercot presents that as implausible.

Support from Transcript:

  • He asks: “How reasonable is it…after 1,900 years, evangelical Christianity is basically unchanged from that of the apostles?”
  • He highlights the contradiction: this is claimed “particularly when…we claim that orthodox Christianity had radically changed only 50 years after the apostles died.”
  • His “cumulative effect” model suggests gradual drift is more realistic than either no drift for 19 centuries or instant total drift in 50 years.
  • His “principle of time” assumes truth precedes error; later-originating doctrine is more suspect than earlier testimony.
  • He emphasizes early proximity: second-century Christians were “only one generation away,” and some had direct apostolic connections.
Discussion Follow-ups What specific story about the post-apostolic church would you have to believe for a 50-year collapse but a 1,900-year preservation to both be true?
