Here’s a photograph of a real sign in front of a church in Leipzig, communist East Germany years before the Wall came down:

It reads ‘open to everyone’. At first many hard-core communists thought it was supposed to be funny, some sort of joke. But over the years more and more people talked about it and followed the invitation, among them many nonbelievers and I quote
“The open to everyone motto united all sorts of different people: those who wished to leave the country and those simply curious; regime critics and members of the Stasi (State Security Police); church staff and SED (Socialist Unity Party of Germany) comrades; Christians and non-Christians. In 1989 the Nikolaikirche was one of the most closely watched localities in the GDR. On 9 October there were about 600 SED comrades and Stasi members among the 2,000 participants in the prayers for peace. Outside was a contingent of the army, strike forces, police and civilian action forces. The prayers took place in an incredible atmosphere of quietness and concentration. At the end there was an urgent appeal for non-violence. When we came out of the church with more than 2,000 people – I’ll never forget the sight – there were ten thousands of people waiting in the square. They all had candles in their hands. “Non-violence” was literally taken out of the church and practiced consequently in the street. That was the very core of the peaceful revolution, a new reality that set new standards and took the state power completely by surprise.
