SOLIDARITY WITH THE WITNESSES IN GERMANY
The brothers in Germany were under extreme pressure, and their fellow servants throughout the earth felt it with them. As the apostle Paul wrote: “If one member suffers, all the other members suffer with it.” (1 Cor. 12:26) This was highlighted by what took place at a special gathering of all congregations on Sunday, October 7, 1934, at 9:00 a.m. At that time a sealed envelope was to be opened. It was the text of a telegram to be sent to Hitler’s government. It read as follows:
“Hitler Government, Berlin, Germany. Your ill-treatment of Jehovah’s witnesses shocks all good people of earth and dishonors God’s name. Refrain from further persecuting Jehovah’s witnesses; otherwise God will destroy you and your national party.”
This telegram was dispatched on the very same day from congregations in 50 different countries, including those in Germany. Imagine the flood of telegrams converging on Berlin on that day! It was not only a warning to Hitler and his party; this was also a demonstration of unity and solidarity of Jehovah’s Witnesses worldwide. As for the outcome, the fate of Hitler and of his political party is well known.
