being made to sing songs about praising jesus as a jew.

I go to a PUBLIC arts school. Currently in preparation for our winter concert, every single, and i mean EVERY SINGLE, song we have received is about praising jesus or other things from the bible. This hasn’t been a problem in previous years, but this year we got a new choir director. I have talked to my counselor and other students about how uncomfortable it is for us that are non christian’s. I know at least 3 other people in my choir who are not christian also feel uncomfortable, one of them complained to my counselor as well. My counselor talked to our department chair and they said that they are not going to change the music. I feel very stuck at this point. I’ve thought about writing an email to my choir director and department chair on how this is making non christian students uncomfortable and that we are a public school not a religious school. I feel like i’m going crazy. I don’t feel like my mom is upset enough about the fact nothings going to be changed. idolatry is literally against judaism. also the fact that my great grandparents were holocaust survivors, left everything behind, came to the states and continued to be jewish despite the trauma from that, makes me even more upset and feel like i shouldn’t be singing these songs. I don’t know what to do. suggestions?
