Regarding the claim that Maria Russell wrote the first 4 volumes of Millennial Dawn:
After thinking about it, I am skeptical of this claim.
It is true that Charles T. Russell did acknowledge the help of his wife in connection with the volumes, and did use an editorial staff, and Maria was Associate Editor without her name attached to her articles.
On the other hand, like Maria, Charles was capable of writing the books himself. He had written the Object and Manner booklet (1877) , and the Tabernacle and its teachings (1881). Maria could not have helped him with Vol. 5 (1899) or the lengthy Vol. 6 (1903).
Charles was probably more familiar with the time proofs than Maria, having preached them with Barbour, and modifying them in the Tower.
If it is true, Maria was the one responsible for originating the "that servant" doctrine and applying to her husband Charles. If she did indeed write the four volumes and knew it, it seems unlikely to me that she would have done this. The volumes at that time were the main means of spreading the "present truth". This would confirm to me that she thought that Charles had written the volumes himself, and not her.
If Charles was as egotistical and demeaning toward women as the judge in the court case determined, than it doesn't seem reasonable to me that he would arrange for his wife to write the books and palm them off as his own. An egotist would have written the books himself.
It is difficult to imagine any person like Charles who thinks they know the Divine secrets of the timing of Christ's invisible presence and the end of society and feels it is their personal mission to tell others, would give up the opportunity to write about it. There is much ego involved in being a prophet, and would have Charles passed up on being the author of these books?
Even if after the bitter court case, Charles still promoted the Studies in the Scriptures, and made the claim that they were the key to understanding the Bible, and necessary for staying in the light. This extremely laudatory promotion of these books is understandable if he wrote them himself, but does not seem credible if Maria wrote them.
John Paton wrote the book Day Dawn around 1880, and Russell promoted the book, but when he and Paton parted company, he no longer did so. If Maria did in fact write the first four volumes, it would seem difficult for Charles to think of them as highly as he said.
What's more, if Maria had in fact written the books, then she and not Charles is responsible for the dogmatic and unqualified statements regarding the chronological predictions, and the fatalistic, inevitable, and total collapse of society and the establishment of the Kingdom. Historically, it makes a difference who wrote these claims. To me, if Maria had in fact written them, it would be lower my estimation of her. Whoever was responsible for writing in this tone was not serving the public interest, and is the worst thing that came out of the Russell movement.
Unfortunately, other than a manuscript, there is little today that could confirm whether Maria's claim is true. The circumstances of their marriage is unusual and even bizarre, and we have a "he said", "she said" situation here.
