*** jv chap. 14 p. 200 "They Are No Part of the World" ***[Box/Pictures on page 200, 201]Practices That Have Been AbandonedThis Christmas celebration at Brooklyn Bethel in 1926 was their last. The Bible Students gradually came to appreciate that neither the origin of this holiday nor the practices associated with it honored GodFor years, Bible Students wore a cross and crown as a badge of identification, and this symbol was on the front cover of the "Watch Tower" from 1891 to 1931. But in 1928 it was emphasized that not a decorative symbol but one’s activity as a witness showed he was a Christian. In 1936 it was pointed out that the evidence indicates that Christ died on a stake, not a two-beamed crossIn their "Daily Manna" book, Bible Students kept a list of birthdays. But after they quit celebrating Christmas and when they realized that birthday celebrations were giving undue honor to creatures (one reason that early Christians never celebrated birthdays), the Bible Students quit this practice too... They should say "Jehovah's Witnesses", not "Bible Students" if they didn't stop celebrating birthdays until 1951.
