only a true bibliophile could've thought of it.
Actually it was a Seventh Day Adventist who first thought of it.
Here's the verse from the KJV:
(Acts 13:42 KJV) And when the Jews were gone out of the synagogue, the Gentiles besought that these words might be preached to them the next sabbath.
Seventh Day Adventism is based around Acts 13:42
Most modern versions say something like:
(Acts 13:42 ASV) And as they went out, they besought that these words might be spoken to them the next sabbath.
Thus, the beginning of King James Onlyism.
The SDA's started it to protect their Seventh Day Adventism, and now it exists in almost every denomination.
You will find no such thing as King James Onlyism before Seventh Day Adventism was invented.
