During his visit to the synagogue in Rome, the pope developed this thought: The Jewish religion is not 'extrinsic' to us, but in a certain way in 'intrinsic' to our own religion. With Judaism, therefore, we have a relationship which we do not have with any other religion. You are our dearly beloved brothers, and in certain way, it could be said that you are our elder brother.
