“During the war, the Church, which knew what was happening, kept quiet,” Reuss adds. “Those people who believe in the God of Israel did the exact opposite of what the Holy Scriptures say. So it is important to us as Christians to speak and shout out against anti-Semitism and against the hatred towards Israel. The best way to understand the meaning of anti-Semitism is to look it in the face, and that’s what we’re doing. We understand the meaning of anti-Semitism and where it can lead, because we look at our family’s history and see what our forefathers did. So coming here is a powerful thing which conveys a message in an excellent way.”
