Did Joseph F Rutherford start three churches?

Answer 1

Joseph F. Rutherford became the second president of the Watchtower Bible and Tract Society in 1917.

Early in his life he was a Baptist, but when he was engaged to his wife to be, who was a Presbyterian at the time, his Baptist minister told him that his wife would go to hell, whereas he, being a Baptist, would still go to heaven. This didn't make sense to him, and he actually turned atheist for a time.

Later, after bible studies with members of the International Bible Students Association (as Jehovah's Witnesses were then called), he was baptised in 1906 with the religion that would later be known as Jehovah's Witnesses.

My research does not indicate that he started (or founded) any church, or religious organization. He left the Baptist church, left off from religion for a time, ad then later joined the IBSA (Jehovah's Witnesses), and became the president of that organization in 1916.
