wagglebee needs to broaden his reading. Alex, you beat me by seconds. I had this ready and was interrupted by a client.

It happened one Wednesday morning in February 1944. Corrie was ill with flu at the time. A Dutchman whom Corrie did not know asked for some money. He said he needed it urgently to save some Jews. Corrie did not feel sure about him, but could not risk letting down any Jews. It turned out later that the Dutchman was working for the Germans. She went back to bed because she was so unwell. Suddenly the buzzer sounded. All the guests piled into the secret room. Some Gestapo officers and two Dutch Nazis burst into the house. They took all the ten Boom family into the living-room. Corrie's brother Willem happened to be in the house that day, as well as some Dutch people who knew nothing about the Jews. One of the Gestapo took Corrie into another room. "Where are the Jews?" he asked. "There aren't any Jews here," answered Corrie. She hated telling lies, but surely that was better than allowing people to be murdered, she thought. The policeman hit her, repeating the question, but Corrie did not answer. "Where is the secret room, them?" he asked, keeping on at her and hitting her again and again. Corrie felt blood in her mouth. She was so ill, and felt faint. "Lord Jesus, help me," she cried out. "If you use that name again, I'll kill you," said the policeman. But he stopped beating her and took her back to the others. Next he started on Betsie. When she came back she also was bruised and bleeding. All this time, German soldiers were searching the house, smashing open cupboards and doors in an effort to find the secret room. But they could not find it, and after half an hour they gave up. "All right," said the officer in charge, "take this lot to the police station, and set a guard outside the house. If anyone is here they will starve to death." At the police station, Corrie and her family had to spend the rest of the day sitting on the floor of a large room. Many other people had been arrested at the same time, including Pickwick. The Dutch policeman named Rolf came into the room. "Let's have it quiet in here," he shouted. "Toilets are outside at the back. You may go out one at a time under escort." Then he bent down quickly and whispered in Willem's ear, "You can tear up any papers you don't want the police to see, and flush them down the toilet." Willem passed this on to the others who needed to know. At home, every evening at about nine o'clock Father ten Boom always held family prayers. Here, under arrest, a group gathered round him to do the same. There was no Bible, but Father ten Boom knew much of it by heart anyway. In his deep voice he quoted some words from Psalm 119: "You are my hiding place and my shield: I hope in your word.... Hold me up, and I shall be safe." His faith in God gave the others comfort and strength.

Please see my responses in 54 and 57.
I had totally forgotten about Corrie ten Boom and her wonderful family. They were true Christian martyrs and models for all of us.
I was completely wrong when I said that no Calvinists had sacrificed everything during the Holocaust.
