Jesus was Jewish. Judaism was our spiritual origin. In Jewish tradition it is the parent's responsibility to ensure that children are educated in their faith, learn a trade, and marry appropriately. That applies to all of us.
Actually, Jesus wasn’t Jewish as he himself proved.
Yes, absolutely. Catholic Christianity is the perfection of Jewish temple worship. The Jews need to convert only insofar as they no longer practice the Judaism of their forefathers. But as the Second Temple was destroyed, it was also rebuilt by Christ. Gaze at the Altar and see Jerusalem in Heaven.
