Whenever we as Christians are confronted with conflicts or tough decision making situations, it is prudent to ask ourselves, “What does our faith say about this?” Jesus stated in his teachings, “I’ve come to change the law but fulfill it.”
So we understand that Jesus was respecter of laws (basically Jewish custom), thereby leaving us an example to he world.
To practically combat anti-Semitism and supersessionism in my community as a Christian is to first be acquainted with history of Judai-Christianity and use my biblical knowledge to educate youths. Much of anti-Semitism and supersessionism comes from lack of knowledge about Judaism of which Christianity has its root.
So we must do justice to history and the political implications of the subject matter and thereby use our experience to resolve this crisis, and honesty in making sure that the historical truth is taught to my immediate associates all the time.
