Terry: Charles Taze Russell's core group of early followers rallied around what?
A NEW BIBLE STUDY METHOD which was detailed Subject by Subject.
The Bible was the center of attention.
What changed?
Russell began shifting appreciation for BIBLE to his OWN writings as superior!
He bragged that a person who used only his Studies in the Scriptures would be far better off than a person who used only the Bible.
This was ADAPTATION and a SHIFT from basic Protestant sola scriptura to CULT control.
To continue in the spirit of 'deconstruction...the 'New Bible Study Method' was modeled after the International Correspondence Schools Home Study Courses.
Two of the early Russell followers (business partners) were textbook writers for ICS. George Fisher and Clayton Woodworth.
I would suggest that your last sentence should read: "This was ADAPTATION and a SHIFT from basic Protestant sola scriptura to corporate control."
