1. Russell was never an Adventist. He did not believe, accept or see as meritorious, Adventist teaching.
2. When Russell met him, Storrs had long withdrawn from Millerite Adventism. He left it amidst great controversy and animosity in 1844.
3. Even while a member of the Life and Advent Union, Storrs did not teach standard Adventist doctrine.
4. Stetson, though a member of the Ohio Advent Christian Conference, was an Age-to-Come believer. By the time Russell met him he was contributing articles to The Restitution, a One Faith (NOT Adventist) journal, and advocating doctrines contrary to main stream Adventism. One Faith belief was not a form of Adventism. They rejected that notion entirely.
5. The sole contribution Adventist contacts made to Russell's faith was an understanding of the state of the dead and the trinity. Both of these views are traceable to Storrs.
6. By late 1872 Russell was reading Age to Come material, not Adventist material. He was well known in One Faith circles, and his acquaintances were men like H. V. Reed, Thomas Wilson, and other contributors to The Restitution.
7. Emphasis on Russell's contacts with Adventists is overblown. No doctrine taught by him is traceable to Adventism. Almost every doctrine he taught is a One Faith or other Age to Come doctrine, usually in opposition to Adventism. This even includes his chronological views. By the time he received them Barbour et. al. had left Adventism. Barbour became a partisan of Mark Allen, an Age to Come advocate. Barbour's chronology is traceable to British Literalist writers, none of whom were Adventists.
8. Pointing to Adventist influences as the most important influences is wrong. There are thousands of pages of Age to Come, particularly One Faith, material that has lain unexplored. Before one points to Adventist antecedents one should read that material. It gives a very, very different picture.
9. While Russell saw the 1843 movement as within God's plan, he saw Adventists as "seriously out of the way." Name ONE doctrine that Russell got from an Adventist - someone who was still teaching Millerite doctrine.
10. Russell saw the 1843/4 movement as within God's plan not because of its doctrines, but because of its place in Barbourite chronology, which pinned the midnight cry to 1859 as a mid-point between Miller and Barbour's set-time.
11. Do not buy into the Russell was a secret Adventist theory. (I admit to thinking another word than 'theory.') He wasn't. From 1871 to 1876 he was a One Faith believer, associating with a One Faith congregation, having a recognized One Faith pastor. His doctrine was a compound of Storrs "ages to come" and "fair chance" doctrines and standard Age to Come belief. It was not Adventist in any respect.
12. Russell self-identified as a Millennarian. That is a term One Faithers applied to themselves. Adventists did not use it.
