The Old Testament shows that God revealed Himself to His chosen people through the prophets and in their history.....plain and simple. The Catechism refuted what you said because you've always claimed that the Israelites of the Old Testament was revealed through the Son. You also said that "I AM" is Jesus. But I told you that both the Father and the Son are "I AM" because there is only one God.
The Jews worship the same God of Abraham whom Christians worship. The only difference is that Christians know the true nature of God because we have both the Old and New Testament whereas the Jews only have the Old Testament. Nevertheless, it is our duty to dialogue with the Jews and all other non-Christians so that they can also come to know Jesus Christ.
After the retreat with the 120 Jewish Rabbis in 2015, the founder of the Neocatechumenal Way, Kiko Argello, was interviewed. He was asked, "At the end of the meeting what has been the reaction of the rabbis?" According to Arguello:
"We received exciting experiences. A Rabbi of Israel, Rabbi David Brodman, started giving an experience that moved the assembly. He spoke of this meeting as a crucial meeting, of this relationship between the Catholic Church and the Jewish world that he never could have expected. He said: "This was my dream. I wanted - and the Lord gives me, at the end of my life - to see these things. " He cited a book by a rabbi who is very important to him; He said that we are in a time when we are experiencing "labor pains" to prepare for the arrival of the Messiah in our midst, and he's already seeing all this; Also in this meeting, he saw it as a preparation for this coming of the Messiah. Then there was another rabbi of Holland who also told his experience as a child he was saved by a Christian family. And also speaking of this meeting, he said: "I have really seen God work in our midst." Another rabbi who said: "I tell you frankly, that I realized something, listening to Kiko. I in my family, in my tradition, I never heard that God loves us ", and said with a force that moved the assembly. "I saw him here, in this house. - He said - I saw him really in the facts: how they welcomed us ... ", in the experiences that I have heard in the groups, how these couples spoke, these families, these brothers of the Neocatechumenal Way, saying with their lives, how God loved them, how he had redeemed them, saved them ... He said: "Well here, I asked my wife: 'But you, for example, have you heard from someone in your life, in the synagogue, this word, that God loves us? '". And his wife said to him: "No, I have not ever heard, ever heard!". And the rabbi said: "Me too ...". Also the experience of Rabbi Greenberg of the United States was very moved. The environment that was created at the end you cannot describe it, really! Then, we also had very familiar times, we had dances ... there was a spirit of communion that was very strong!"
The Jewish Rabbis were fascinated when they heard the Gospel that some felt so moved by it. They have never read the Holy Bible. They have never heard about the "Love of God." Why? Because the Love of God can only be found in the New Testament. Since 2015, we have been holding these retreats with the Jewish Rabbis at their request. And the Catholic Church continues to share the feast of the Epiphany with the Jews every year so that they can come to know Christ.
