Jehovah's Witnesses In The Divine Purpose, page 22, states:
"For this reason 1879 was a turning point in the work. This little group, headed by C . T. Russell, had now been tested and had been found fit to undertake the great preliminary campaign leading up to the climax expected in 1914."
If the Bible Students were tested and found fit in 1879, then birthdays, Christmas, and other practices had already been approved by God.
Some people ask, if the Bible Students were found fit in 1879, then why did they need to be tested again in 1918 or 1919?
Answer! Because the Watchtower makes this stuff up as they go along and forces it down the throats of JW's. JW's just don't realize that the carrot they have been chasing after for so many years, is already rotten and stinks to high heaven.
Atlantis!
