Thoughts to Ponder

Thoughts to Ponder is a weekly invitation to think dangerously and question passionately. Drawing on the Torah portion, classical Jewish sources, philosophy, and the crises of contemporary life, Rabbi Cardozo challenges religious complacency and spiritual comfort. These essays are written for readers who seek a Judaism that disturbs, questions, and ultimately deepens the human encounter with God and responsibility.

  • A Summary to Nathan Lopes Cardozo’s new Hebrew book: Halacha Ka-Mered

    In Halacha by Rabbi Nathan Lopes Cardozo

    Rabbi Pachter’s new introduction to the Hebrew edition of Jewish Law as Rebellion is very helpful in facilitating a better understanding of the book and of my philosophy. I have translated it into English from the original Hebrew and will be posting it in the coming weeks. To increase the clarity of some of the ideas, I am posting here a kind of “introduction” to Rabbi Pachter’s introduction for those who are not familiar with my perspective on Judaism and Halacha.

  • Parashat Chukat – The Red Heifer and the Meaning of Life

    By Rabbi Nathan Lopes Cardozo

    This week’s parashah opens with the perplexing law of the Red Heifer, whose ashes purify one who has come into contact with the dead. This strange ritual requires that “a red cow without blemish, in which there is no defect and on which no yoke has been laid” be slaughtered, then burned and its ashes mixed with water. This water would be held in reserve to be sprinkled over an individual who had come into contact with a corpse and was consequently ritually “impure”. Even stranger is the fact that the priest who prepares this purifying water, by his involvement with the preparation process, become impure! This law is held up as the exemplar of a “Chok”—a commandment for which no obvious rationale can be found. Such a law is very different from the “Mishpatim”—those commandments whose moral or intellectual underpinnings are clear and reasonable. What are we to make of this “irrational law” of the Red Heifer?

  • Rabbi Yochanan ben Zakai and the Portable Homeland

    By Rabbi Nathan Lopes Cardozo

    After this war is won, the next great challenge facing the State of Israel will be the possibility that its soldiers will one day refuse to serve and defend this country. How long will we be able to rely on the Israeli army if its combatants do not realize what it is they are fighting for? It is important that they know that they are defending an idea and a holy mission which far surpasses the defense of a piece of land!

  • The Blessing which can turn into a Curse

    In Parashat Behar by Rabbi Nathan Lopes Cardozo

    The Torah tells us that we shouldn't worry about leaving the land untilled in the Shmita year, because He will bless the sixth year with a crop sufficient for three years. The question is: why has this blessing of abundance in the sixth year not been renewed?

  • The Wisdom of the Wicked Son

    In Passover by Rabbi Nathan Lopes Cardozo

    As Pesach approaches, there is something very important that we must understand. It is that the wicked son in the Haggada is in fact the wisest and most honest of the four sons. Why? Because he is the one who is asking the most important question of all!

  • The Miraculous Nature of Normality

    In Jewish Thought and Philosophy and Parashat Tzav by Rabbi Nathan Lopes Cardozo

    The most challenging question in all of life is what do you do, and what do you believe when you are not sure. It is this question that moves the scientist, the philosopher, and most of all the religious personality. We must destroy the security of all conventional knowledge and undo the normalcy of all that is ordinary. To be religious is to realize that no final conclusions have ever been reached, nor will ever be reached.

  • Spinoza, the Alter Rebbe, and the Eternal Fire

    In Jewish Thought and Philosophy, Spinoza and Parashat Tzav by Rabbi Nathan Lopes Cardozo

    The Talmud states that all the sacrifices were consumed by a heavenly fire, not by the fire lit by the Cohanim. This seems to imply that there was absolutely no need to keep the human fire on the altar burning so as to consume the sacrifices. So why were the Cohanim commanded to keep the fire on the altar lit? It seems that an answer may be found in contrasting the teachings of two very different thinkers--Spinoza, who famously did not believe in miracles, and the Alter Rebbe, who believed the existence itself is a miracle.

  • Prayer, Sexuality, and the Pleasure Principle

    In Jewish Thought and Philosophy and Parashat Metzora by Rabbi Nathan Lopes Cardozo

    Why are males and females physically attracted to each other? What is there in their physical appearance that makes them so excited that they want to be intimate, to the point where they consider this a great joy? The Sages of Israel understood the enormous power of sex and its immense challenges. Unlike other religions, such as classical Christianity, they never saw sexuality in a negative way. This is because sexual attraction is a reflection of Divine love.

  • Unity, not Uniformity

    Changing the discourse in Israel

    In Maimonides and Parashat Metzora by Rabbi Nathan Lopes Cardozo

    In these difficult days, we have a moral obligation to create an environment for respectful discourse. We should all do what we can to provide our families, our friends, and our children with the tools to control how we speak about and to one another. The noble teachings of the Jewish Tradition could greatly help with this.

  • The Strolling Light of Shabbat

    The art of creative abstinence

    In Parashat Emor and Shabbat by Rabbi Nathan Lopes Cardozo

    When the light of the setting sun announces the entrance of Shabbat, a miracle happens: the light assumes the quality of light in a Rembrandt painting. The light slows down. It strolls! There is no way to see the strolling of the light unless one actually opens the door to let it in. One cannot talk about mystery. One must be grasped by it. And that is only possible when insight and creative inaction become one.

  • Putting God on Trial: The problem of Divine Collateral Damage

    In Jewish Thought and Philosophy, Theodicy and Parashat Acharei Mot by Rabbi Nathan Lopes Cardozo

    The Jewish Tradition never told people not to question divine justice. Such questions are not only legitimate, they are holy because they rise from a deep realization that God is righteous and at the same time honest enough to admit that He is at fault.
