Let's see how people use "apologetics" for this.
Christians believe that Jesus was a person until the day that he died on the cross.
Christians believe that Jesus died for our sins.
Jesus was a Jew who did not know of the Christian follow-up to the bible that was written more than 300 years after his death. Therefore, he would have believed in Deuteronomy 24:16.
"A father (parent) shall not die for the sin of his children. A child shall not die for the sin of his father (parent). No person shall die for the sin of another person."
Assuming that Jesus believed this, which we must, he would want all Christians to become Jewish.
Being apologetic does not mean accepting something that is in complete opposition to one's faith.
