It was also the case by the late 20’s and thirties that all the mainline denominations seminaries shifted over to “higher criticism”. The consequence of this was that the person of Christ was degraded from being both fully God and fully Man to being just a good man. This was a heresy that had been gaining momentum since Newton embraced it back in the late 17th century. Its first incarnation was back in the 4th century with the Arian Heresy for which which the Nicean creed was written.
The 1920s and ‘30s were the period in which the faculties of nearly all colleges were completely purged of pre-industrial faculty by the “silent artillery of time.”
By 1930, nearly every professor at every university was a lifelong product—from “kindergarten” on—of the German secular research university model.
