Jesus Christ was a Jew in the Bible, but he never behaved like them. We cannot show clearly the paternal lineage of Jesus Christ.
We know that Mary gave birth to Jesus Christ, but even though she was among the Jewish people where he was born, it does not prove that they know the true father of Jesus Christ. Although many people can confuse themselves as Joseph was his father but that is not the real issue here. So at the time we can't know about that.
Jesus Christ never had that biological father that he is the true son of God. So we should not be like the Jewish. The Bible says that they were really offended because Jesus Christ, they saw the miracle that Jesus Christ performed and they were angry. They were supposed to obey the teaching of Christ but they questioned it every time.
Jesus Christ does not have an earthly father. He is the true son of God.
