Talking about Jesus can be hard in an interfaith family. But there are more books talking about Jesus from a Jewish and from a shared perspective. Take a look here.
A Catholic woman once told me that Jesus was her dearest friend, that he has stood by her through very difficult times. In her process of determining whether she wanted to raise her children as Jews it was important for her to work within her sense of Jesus. She talked at length to her priest and to her husband’s rabbi. The couple took a year of practicing both religions in their home before they decided.
