The family of John Birch was Presbyterian till he was 12 when the church his family attended started teaching evolution. They found a Baptist church where they accepted credo baptism.
But theological liberals in the Baptist seminary were teaching evolution and discounting the miracles in the bible. JB had top grades, and was reluctant to make waves, till a preacher of righteousness came to town and John was convicted by his message. John started a Bible Study Fellowship club and preached in the open each week. An older man encouraged them to expose the professor who taught that salvation was merely a salvation from wrong willing, acting and improper feeling and denied the miracles in scripture. John sent out the three hundred letters, to Baptist pastors and exposed the heresy of professors at their Baptist Seminary.
John was harangued by students for being so intolerant.
Pastors were upset that the school was not orthodox. A church court trial was held with five judges. Thirty were saying John and five dissidents should be expelled. News reporters covered the story of students who were attempting to get Professor Freedman to resign for teaching heresy: evolution, discounting the miracles, and saying the Bible contradicted itself. The professor was exonerated, accepted as “a good Baptist.”
Outside the meeting, the “unholy” John Birch and his 12 friends faced a sign, “Lynch St. Birch."
