I was reading some obscure document from the early 20th c. a little while ago that used the term "PINO" (Presbyterians In Name Only) and I cannot, for the life me, remember what document that was.
Interwebs search turned up nothing.
Bummer.

This is what I got from AI.
The term "PINO" (Presbyterians in Name Only) was popularized in the early 20th century by a series of articles and books written by Presbyterian minister and author, John D. Rockefeller Jr.
In his book "That Man: An Autobiography," published in 1953, Rockefeller writes about his experiences within the Presbyterian Church and his observations on the growing trend of nominal or "PINO" Presbyterians. He defines PINO as individuals who attend church regularly but do not truly live out their faith.
Rockefeller's use of the term PINO was significant because it highlighted a perceived problem within the Presbyterian Church and other Christian denominations at the time - the growing number of people who were nominally affiliated with a particular church or denomination but did not actively participate in its practices and teachings.
Since Rockefeller's time, the term PINO has been used by some to describe individuals or groups within various denominations who do not fully embrace the principles and practices of their faith. However, it is important to note that the use of this term can be subjective and may not always accurately reflect the full complexity of an individual's or group's beliefs or practices.
