Jesus lived a fully human life while also being divine. He experienced human joys and sorrows to sanctify human experiences. His life fulfilled Jewish expectations of the Messiah by obeying Jewish law and traditions. Jesus brought unity among divided groups in Israel through his teachings of love and by healing the sick of all backgrounds. The Mass allows Christians today to access the salvation won on the cross through the sacrifice of Christ's body and blood, which has its roots in the Jewish Passover tradition.
