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.
Just not on Pessah
In Halacha, Jewish Thought and Philosophy and Passover by Rabbi Nathan Lopes Cardozo
Why is it prohibited to eat or to possess chametz (leaven) on Pessah? What is there in the nature of leaven that makes it forbidden, and why only on Pessah? The Talmud offers an insightful answer.
A tongue in cheek look at the Jewish attitude toward sports
To run around a soccer field behind a ball is not yet sport. Only when it is the result of creativity, it becomes the definition of being human.
On Hypocrisy and Hiding behind the Kashrut Laws
In Education, Halacha and Parashat Shemini by Rabbi Nathan Lopes Cardozo
Why did the Torah need to state that some non-kosher animals chew their cud or have cloven hooves? Would this not suggest that perhaps they are, after all, kosher!
The Jews are a nuisance. They break the rules of history, survive against all odds, and contribute disproportionately to the world. No wonder they are so difficult to tolerate. This essay offers a bold and provocative reflection on why anti-Semitism persists—and what it reveals.
A Dangerous Mixture
In Education, Halacha, Jewish Thought and Philosophy and Parashat Mishpatim by Rabbi Nathan Lopes Cardozo
One of the most puzzling laws in Judaism is the prohibition of mixing milk and meat. Strangely enough, this mysterious law has had the greatest influence on the daily life of Jews for thousands of years, right up to this very day.
Reply to a Jerusalem Rabbi
In Education, Jewish Thought and Philosophy and Spinoza by Rabbi Nathan Lopes Cardozo
Should Judaism fear its heretics? The centuries-old ban on Spinoza raises a deeper question: is banning an admission of strength—or of insecurity? This essay challenges us to reconsider whether a confident tradition needs protection from ideas, or whether it should confront them head-on.
In Education and Halacha by Rabbi Nathan Lopes Cardozo
The foremost point of departure in any halachic decision must be that all people are created in the image of God and that all human life is holy. We forget this principle at our own peril
A historical lesson from the Exodus
In Parashat Bo and Passover by Rabbi Nathan Lopes Cardozo
When reading the story of the Exodus from Egypt, we are confronted with a strange phenomenon: the mashchit (destroyer). What was this mysterious threat?
In Liturgy & Ritual and Parashat Vayetzei by Rabbi Nathan Lopes Cardozo
How does man dare to speak to God, the Master of the Universe? The presumption that man can just open his mouth and believe that God will listen to him is unrivaled impertinence. When someone wishes to get an audience with the Queen, much paperwork has to be done, many meetings are held by ministers and officials, and security issues are considered.
It Is Time to Lift The Ban
In Jewish Thought and Philosophy and Spinoza by Rabbi Nathan Lopes Cardozo
A ban is a sign of fear, and since when is Judaism afraid? While the ban may have been necessary in the seventeenth century, today it only embarrasses Judaism.
A tongue-in-cheek prophecy
We will soon have to expand our borders at the request of millions of Europeans, Americans and possibly many others who will wish to come on Aliyah.
Halacha is the external garment of an inner spiritual process that should be stimulated by those very halachic acts. For that to occur, much more has to be accomplished. To become religious is to face opposition, even from oneself – to dare, to defy, and even to doubt.
