First I can help combat antisemitism and supersessionism by educating myself on the history while also sharing what I know with others. Additionally, being careful with how we teach the younger generation about Jesus’s death is important. We need to make sure to not blame anyone because at the end of the day, it was in God’s will for Jesus to die on the cross for our sins. This story again proves that God never lets any bad moment be used for evil but he uses it for good.
Additionally, I think it would be helpful to have conversations with Jewish people. Sometimes we hold these preconceived notions about people and their ideas. We generalize them and assume we understand their perspective based on information shared with us or based on assumptions. Having a conversation with Jewish people and seeking to understand them and their culture is a great way to connect on a smaller scale.
