early 1877. It articulated ideas that remained the teachings of Russell's associates for the next 40 years, many of which are still embraced by Jehovah's Witnesses: it identified a 2,520-year-long era called "the Gentile Times", which would end in 1914, and broke from Adventist teachings by advancing Russell's concept of "restitution" — that all humankind since Adam would be resurrected to the earth and given the opportunity for eternal perfect human life. Russell claimed it was the first book to combine biblical end-time prophecies with the concept of restitution. It discussed the concept of parallel dispensations, which held that there were prophetic parallels between the Jewish and Gospel ages, and suggested the "new creation" would begin 6000 years after Adam's creation, a point in time he believed had been reached in 1872.

Russell, Barbour and Paton began traveling to hold public meetings to discuss their beliefs. For Russell, it was not enough: "Noticing how quickly people seemed to forget what they had heard, it soon became evident that while the meetings were useful in awakening interest, a monthly journal was needed to hold that interest and develop it."

He began publishing his own monthly magazine, Zion's Watch Tower and Herald of Christ's Presence (now known as The Watchtower), which he sent to all the subscribers of the Herald, disputing Barbour's teaching.

Three years later, on December 15, 1884, Russell became the president of the society when it was legally incorporated in Pennsylvania. He said the corporation was "not a 'religious society' in the ordinary meaning of this term," explaining: "This is a business association merely ... a business convenience in disseminating the truth." Russell began to write a stream of articles, books, pamphlets and
