Conversion to Judaism is more than the adoption of a new identity; it means acceptance of a demanding covenant. It means joining a people with a unique history and a lifelong argument with God and tradition. The convert chooses obligation freely—an act that challenges those born into it to reconsider their own commitments. Conversion reminds us that Judaism is not inherited passively; it must be embraced consciously, through study, struggle, and moral resolve.
Would You Decide to Become Jewish?
In Converting to Judaism, Franz Rosenzweig, Moses, The Kotzker Rebbe and Parashat Yitro by Rabbi Nathan Lopes Cardozo
Yitro gave up power, honor, and certainty in his search for truth. But would we choose Judaism if we were not born into it? Yitro challenges both the religious and the secular to ask whether their Jewishness is inherited habit — or a courageous, ongoing choice.
In Converting to Judaism, Parashat Emor and Parashat Ki Tisa by Rabbi Nathan Lopes Cardozo
What exactly is Divine Law? And do human beings have any say in what the Law is to be?
There are probably billions of people who are full-fledged “soul Jews” but don’t know it, and very likely never will. Perhaps it is these Jews whom God had in mind when He blessed Avraham and told him that he would be the father of all nations and that his descendants would be as numerous as the stars in the sky and the grains of sand on the seashore.
In Defense of Heresy
In Converting to Judaism, Education, Jewish Thought and Philosophy, Moses and Parashat Shemot by Rabbi Nathan Lopes Cardozo
Judaism was born out of opposition, rebellion and protest. It overthrew and outlived mighty empires and gave the world a radically new understanding of itself. Judaism has nothing to fear. It has prevailed over all those who criticized it but has also learned much about itself by listening to opposing voices. Through these voices, it has been able to sharpen its own claims and if necessary change its mind when the inadequacy of these claims has become clear. Only in this way will it continue to play a central role in the future of mankind.
An Open Letter to Israel's Chief Rabbis
In Converting to Judaism and Jewish Thought and Philosophy by Rabbi Nathan Lopes Cardozo
The first convert and Jew, Avraham, was only asked to observe a few of the commandments. In the same way, we should allow potential converts this option to slowly work their way up to Sinai.
The Birth of Non-Jewish Jewish Communities
In Converting to Judaism and Jewish Thought and Philosophy by Rabbi Nathan Lopes Cardozo
Today, Israel has many thousands of immigrants who are of Jewish descent, yet not halachically Jewish. Should we convert them even though we know that they will not live a fully committed Jewish life? Or should we abandon them, basically ignoring and excluding them as we do now? I believe there is a third way, a way of reconciling these difficulties.
In Converting to Judaism and Halacha by Rabbi Nathan Lopes Cardozo
Just as a human being who’s never had an encounter with classical music won’t know what he’s missing until he is introduced to Mozart, Beethoven or Bach, so it is with Judaism. But it all depends on who is playing the music.
In Converting to Judaism and Jewish Thought and Philosophy by Rabbi Nathan Lopes Cardozo
What makes one a Jew? Being born to a Jewish mother? Converting to Judaism? Not really. It is living by the spiritual order of Judaism that makes one a Jew; living through the Jews of the past and with the Jews of the present and future. We are Jews when we choose to be so; when we have discovered Jewishness on our own, through our search for the sacred; when we fight the never-ending spiritual struggle to find God, realize that the world needs a moral conscience, and carry that exalted burden so as to save the world and provide it with a mission.
Solving the Conversion Crisis - Part 3
In this essay I reluctantly suggest new criteria for conversion. They must be seen as a response to the need of the hour in which our people finds itself. This is especially true for the State of Israel to which tens of thousands of people of Jewish descent made aliyah, primarily from Russia, yet who are not halachically Jewish.
In Converting to Judaism and Jewish Thought and Philosophy by Rabbi Nathan Lopes Cardozo
Israel has been confronted with the plight of hundreds of thousands of people who made aliyah, mostly from Russia, who are children of mixed marriages or who have other Jewish ancestry, such as Jewish grandparents. Most of them are not halachically Jewish since their mothers are not Jewish. Yet many of them would like to become Jewish. The problem, however, is that the majority do not want to commit themselves to a halachic way of life.
In Converting to Judaism and Jewish Thought and Philosophy by Rabbi Nathan Lopes Cardozo
Judaism and the Jewish people are intertwined and interact in ways which nobody can fully grasp. Are we a religion, or a nation? If we are a religion, how can it be that somebody who does not believe in God or refuses to observe even one commandment still remains Jewish as long as he or she is born to a Jewish mother? And if we are a nation, how does religion come in, telling us who belongs to the nation and who does not? Any attempt to find a solution to this problem will always fail. This is one of the greatest mysteries of Jewish identity.
In Converting to Judaism, Jewish Thought and Philosophy and Shavuot by Rabbi Nathan Lopes Cardozo
As long as Judaism is taught as merely a luxury, something extraneous to life, it will be of little importance in the eyes of those who are asked to become Jewish. But when we teach it as being indispensable, it will become life itself and will make waves in the souls of all those we approach.
