I see the "barking exercises" (as Stone called them) and the falling down and writhing on the ground at Cane Ridge to be mass hysteria. The good that Stone and Campbell did was throwing off the accretions of the Catholic church and getting back to basics. Unfortunately, they could not agree on just what the basics were. Campbell's inflated impression of himself didn't help matters. I have been to Cane Ridge several times and view it as the place where we started to use the Bible for our doctrine rather than the teachings of men.
With regard to the DoC/CoC split, we started to go our separate ways during the Civil War. With no central headquarters it took us longer to divide than it would a hierarchical church but by the early 1900s there was no question that two separate denominations existed (I am willing to call the CoC a denom).
Hah! Just the answer I expected. I could have pre-written it. So, Barton Stone used his hypnotic powers to cause these people to create mass hysteria in the name of the Lord. Why would you claim him as a founder?
Your teachings are of men.
Who came up with the six step program and then whittled it down to five so they could be numbered along with the use of the digits of a single hand? Hint: It was a man.
Who said that the church had stopped preaching water baptism for the remission of sins and that teaching needed to be restored? Hint: It was a man.
Who claims that it is a sin to have a kitchen in the building? Hint: Men.
Who claims it to be a sin to use multiple communion cups? Hint: Men.
You mentioned the Civil War. Good. Alexander Campbell was a slave owner. He was arrested in Scotland when he went back there for a visit. Students at his Bethany College nearly burned down the place in protest of his having been a slave owner.
Church of Christ folk give me a chuckle. They are selective about Bible verses (proof-texting) and they are also selective about which aspects of their history they will claim and which aspects of their history that they deny.
Church of Christ folk then go to Cane Ridge to celebrate mass hysteria along with the birth of the one true church.
