What is Orthodox Judaism? A Complete Guide
An insider's guide to Orthodox Judaism — what Orthodox Jews believe, how they live, and what makes this ancient tradition unique in the modern world.
Quick Answer
Orthodox Judaism is the most traditional branch of Judaism. Orthodox Jews believe the Torah — both Written and Oral — was given by G-d at Mount Sinai and remains fully binding. They follow halacha (Jewish law) governing daily life, including Shabbat observance, kosher dietary laws, and modest dress.
Let me tell you how this website came to be. I am an Orthodox Jewish woman, raised Hasidic in Brooklyn, Bais Yaakov educated, mother of a large family, and I work as a 5th grade teacher. Every September, when a new school year starts, I get the same wide-eyed questions from colleagues and parents who are not familiar with our way of life. "Why can't you eat that?" "What happens if you flip a light switch on Saturday?" "Wait, you don't have a TV?"
I found it fascinating, how little people know about Judaism. Not just the non-Jews — even Jews from other backgrounds had so many questions. And I realized that most of what people "know" about Orthodox Jews comes from TV shows and headlines, which usually get it wrong.
So I decided to do something about it. This site is for everyone. For newbies who want to learn about Orthodox Jews, through observing Orthodox Jews who want to learn more about their own heritage. Whether you are my curious coworker, a college student writing a paper, or a Jewish person exploring your roots — pull up a chair. Let me tell you about my world.
What Do Orthodox Jews Believe?
Orthodox Judaism is the most traditional branch of Judaism. We believe that the Torah — both the Written Torah (the Five Books of Moses) and the Oral Torah (later recorded in the Talmud and other works) — was given by G-d to the Jewish people at Mount Sinai and remains binding in every generation.
Unlike other Jewish denominations that adapt or reinterpret Jewish law for modern times, Orthodox Judaism holds that halacha (Jewish law) is eternal and authoritative. This does not mean we are stuck in the past — it means we navigate the modern world while maintaining ancient commitments. I carry a smartphone, I shop online, I use technology every day. But I do it all within a framework that has guided Jewish life for thousands of years.
At the core of what we believe:
The Torah is divine. We believe the Torah was given directly by G-d to Moses. Every word is sacred and purposeful. This is the single most important distinction between Orthodox and other Jewish denominations.
Halacha (Jewish law) is binding. The 613 commandments in the Torah, as interpreted by the Talmud and later rabbinical authorities, govern daily life. These cover everything from what you eat to how you do business to how you speak about other people.
The Oral Torah is authoritative. Alongside the Written Torah, G-d gave Moses an oral explanation of the laws. This was passed down through generations and eventually recorded in the Mishnah and Talmud. When I teach my students about Torah Sheb'al Peh (the Oral Torah), I tell them: the Written Torah is like the notes from a lecture, and the Oral Torah is the lecture itself. You need both.
Awaiting the Mashiach. We believe in the eventual coming of the Mashiach (Messiah), who will rebuild the Holy Temple in Jerusalem, gather all Jews to Israel, and usher in an era of peace. This is not abstract theology for us — it is a living hope that shapes how we see the world.
Different Types of Orthodox Jews
One of the things I most want people to understand is that Orthodox Judaism is not a single monolithic group. There is tremendous diversity within it, and I have seen it firsthand.
Modern Orthodox
Modern Orthodox Jews fully observe halacha while actively engaging with secular society. They attend universities, pursue professional careers, and participate in broader culture — all while keeping Shabbat, eating kosher, and following Jewish law. They typically wear modern clothing, though married women cover their hair and dress modestly. I have Modern Orthodox friends who are doctors, lawyers, tech entrepreneurs — and they are shomer Shabbat down to the last detail.
Yeshivish (Litvish)
Also called "Black Hat" or Lithuanian Orthodox, this community places enormous emphasis on Torah study. Men often spend years in yeshiva (Torah academy) before and sometimes after marriage. They tend to dress in black suits and white shirts, and their social lives revolve around the yeshiva and synagogue community. The depth of Torah scholarship in these communities is extraordinary.
Hasidic
This is the world I come from. Hasidic Jews follow the teachings of specific rebbes (spiritual leaders) who lead distinct courts or dynasties — Satmar, Lubavitch (Chabad), Breslov, Belz, Ger, and many others. Each group has its own customs, style of dress, and spiritual emphasis. Hasidic Judaism emphasizes joy in worship, closeness to G-d, and the spiritual dimension of everyday actions. Growing up Hasidic in Brooklyn gave me a deep appreciation for the warmth and intensity of this life.
Sephardic Orthodox
Sephardic Jews trace their ancestry to Spain, North Africa, and the Middle East. Their halachic traditions differ in many details from Ashkenazi (European) Orthodox Jews — different prayer liturgy, different customs, and different rabbinical authorities. Prominent Sephardic rabbis include Rabbi Ovadia Yosef and the Ben Ish Chai. The Sephardic communities I know have an incredible warmth and hospitality that is all their own.
Daily Life of an Orthodox Jew
People are always curious about what a regular day looks like. So let me walk you through it.
Morning: The day begins with Modeh Ani, a prayer of gratitude said before even getting out of bed — literally the first words on your lips are "thank You." Ritual hand-washing follows. Men pray Shacharit (morning prayers), typically wearing tefillin (phylacteries) and a tallit (prayer shawl). In my house, mornings are a beautiful chaos of getting children dressed, fed, and out the door with their lunches packed (kosher, of course) and their davening done.
Throughout the day: Blessings are said before and after eating. Business dealings must follow ethical guidelines outlined in halacha — honest weights, fair prices, no deceptive practices. Interactions between men and women follow modesty guidelines. When I am at school teaching my 5th graders, I am constantly fielding questions from colleagues about these things. "Why did you just whisper something before eating that apple?" It opens up the best conversations.
Evening: Mincha (afternoon) and Maariv (evening) prayers bookend the day. Many men have a set time for Torah study, either at a synagogue or at home. In our house, evenings are homework time, story time, and then the quiet that settles over a house full of sleeping children — which is its own kind of blessing.
Shabbat: From Friday evening to Saturday night, we completely cease work. No driving, no cooking, no using electronic devices. Instead, the day is filled with prayer, festive meals with family, Torah study, and rest. It is the highlight of every week, and I honestly start looking forward to it by Tuesday.
The Heart of It: Family
If I had to sum up Orthodox Jewish life in one word, I think that word would be family. We are very family oriented and lead warm and loving large families. My children are everything to me — they are not an accessory to my life, they are the point of my life.
In Orthodox communities, family is not just important — it is the foundation of everything. The Shabbat table is the center of the home. The holidays are family events. Milestones — a bris, a bar mitzvah, a wedding — are celebrated with the entire extended family and community. And the community itself functions like an extended family. When someone is sick, meals appear at the door. When someone has a baby, the community rallies. When someone is sitting shiva (mourning), the house is never empty.
This is the part that is hardest to explain to people who have not seen it. The depth of connection, the warmth, the sense that you are never alone — it is real, and it is beautiful.
Common Misconceptions
Let me address the things I hear most often, especially from my colleagues at work.
"Orthodox Jews are all the same." As I described above, there is enormous diversity — from Modern Orthodox professionals in Manhattan to Hasidic communities in Brooklyn to Sephardic families in Jerusalem. We do not all dress the same, eat the same food, or follow the same customs. What unites us is our commitment to Torah and halacha.
"Orthodox women are oppressed." This is the one that frustrates me the most, because it is so far from my experience. Orthodox Jewish women have distinct roles, and yes, those roles are different from men's. But different does not mean lesser. I run my household, I manage our finances, I teach full-time, I am raising a family, and I am building this website. The women I know in my community are strong, educated, and deeply respected. Our role is valued precisely because it is so essential.
"Orthodox Judaism is anti-modern." I am writing this on a computer. I used the internet to research it. I will probably check my email after I finish. We use technology, pursue education, and engage with the world. The key distinction is that we do so within the framework of halacha. You will find Orthodox Jews who are doctors, lawyers, scientists, entrepreneurs, and artists.
"It's all about restrictions." This is the biggest misconception of all. While halacha does include many laws about what we cannot do, we experience these as a framework for a meaningful, purposeful life — not as burdens. I like to tell my students: think of it like the rules of a game. Without rules, there is no game. The rules are what make it possible to play. The restrictions create space for deeper connection to G-d, family, and community.
Why I Do This
Some people are born into Orthodox Judaism and stay. Some discover it later in life. Those who become Orthodox as adults (known as baalei teshuva) often describe being drawn to the depth of study, the warmth of community, the clarity of purpose, and the richness of a life lived according to an ancient tradition.
I was born into it. I stayed because of what I see every day — the beauty of a Shabbat table full of children singing, the power of a community that shows up for each other, the deep satisfaction of a life built on something eternal.
And I made this website because I want you to see it too. Not to convince you to become Orthodox — that is not what this is about. But to understand us. To see past the headlines and the stereotypes. To know that when you see an Orthodox Jewish family walking to synagogue on a Saturday morning, what you are seeing is a family that chose this, that loves this, that finds meaning in every part of it.
Whatever brings someone to Orthodox Judaism, what keeps them is usually the same thing: a life that feels deeply meaningful, connected, and whole.
