That he personally had such battles with demons is documented by his own testimony of it at the 1913 Convention of the Bible Students in Asheville, North Carolina. A record of his statements is recorded in the 1913 convention report put out by the Society. His confession came during his talk on the Vow. He began by saying:
I WISH to speak to you of something that I certainly never intended mentioning at this convention. I presume you have all taken the vow, but perhaps some of you have not.
He said he didn't accept the Vow at first and thought it was something Russell "brought up himself" and that he wouldn't accept it unless he found it in Scripture. He then says:
Then began my troubles. I began to pray and to fight it in my own way with the Scriptures. After a few months the Scriptures apparently began to open up... demonstrating its unscripturalness. I thought that... Brother Russell was wrong...
After corresponding with Russell on the issue he said his nonacceptance of the vow led him to eventual demon possession and even automatic writing:
There was a time for five consecutive nights when I never slept a wink; then came a time when the strain was too much; my mind became unbalanced, and I came directly under the influence of evil spirits, so much so that for three days I was as completely under demonical control as was Mrs. Eddy when she wrote "Science and Health."
Previous to this time I had prepared a 36-page book against the Vow, printed in double column, in which all scriptures which seemed to be directly or indirectly against the Vow were arranged. I know now that all these Scriptures were suggested to my mind by the evil spirits. One of the suggestions was... (and this I believe was a truth, for these "lying spirits" do sometimes tell the truth) that in the fifteenth chapter of Numbers where it mentions the "Ribband of blue," it had reference, anti-typacally, to the Vow. But then these lying spirits turned the truth into a lie by claiming that the Vow had been suggested to Brother Russell by the evil spirits. See how clever they were! [4]
