I believe that the greatest weapon is knowledge.
1. Knowledge of both sides of the story. What the Jewish community says, their culture and their worldview and also what they say about them.
2. Knowledge about how all this started and how it can be prevented. Knowing the roots of the problem is very important, so we don’t waste time fighting symptoms of a much deeper disease.
3. Knowledge of how it happens nowadays. Even in a modern society full of connections, we might think that it is impossible for someone to have this kind of prejudice, but understanding why this kind of thing still happens is the most important thing to do.
4. Biblical and theological knowledge, would definitely help to open the eyes of a community if they understood that Israel is still God’s chosen people and the church has not replaced them.
And finally, know what can be done to prevent this, stand up as a voice against any kind of prejudice, and inform others of what can and should be done.
