The Quest Begins
Same roots, different paths: where Judaism and Christianity meet and where they part.
Step 1 of 5 · about 5 min left
Welcome to the trail
Judaism and Christianity are family. They share a Creator, a story that begins with Abraham, and a library of sacred books. Yet on several big questions they give very different answers.
This is a Jewish apologetics course. Apologetics comes from the Greek word apologia, “a reasoned defense.” It has nothing to do with saying sorry! It means explaining why Judaism believes what it believes, with the Hebrew Bible as our map.
“But from there you will seek the LORD your God, and you will find Him if you seek Him with all your heart and with all your soul.”
Deuteronomy 4:29Key idea
Our goal is understanding, never insults. Christian friends are welcome here, and each belief is described the way its own followers describe it.
What we share
Before we look at differences, let's look at the common ground. It's bigger than many people think.
Common ground and distinct beliefs
Only in Judaism
- Oral Torah (Talmud)
- Sabbath on the seventh day
- 613 commandments
Shared by both
- One Creator God
- The Hebrew Scriptures
- Abraham, Moses, David
- Ten Commandments
- “Love your neighbor” (Lev. 19:18)
- Prayer and repentance
Only in Christianity
- New Testament
- The Trinity
- Jesus as Messiah and Savior
One library, two catalogs
Christians call the Hebrew Scriptures the Old Testament. Jews call them the , a name built from the first letters of its three parts: Torah (Teaching), Nevi'im (Prophets), and Ketuvim (Writings).
Counting the books
Jewish canonChristian canonsSame text, different count. Protestant Bibles split books like Samuel and Kings in two and count the twelve minor prophets separately. Catholic Bibles add seven books that are not in the Hebrew canon.
So when Jews and Christians debate, they often quote the very same verses. The real question is how to read them.

Shared historyJewish milestoneChristian milestoneDates marked c. are approximate; the early dates follow Jewish tradition. Not drawn to scale.
Jesus and his first followers were Jews. Over the next three centuries, Christian teachers formalized beliefs, such as the Trinity, that Jewish teachers saw as contrary to the Torah. By the Council of Nicaea in 325 CE, the two paths had clearly separated.
Pack your CLUE
Four tools for every stop
Context
Read the whole chapter, not just one verse.
Language
Check the Hebrew when a translation seems surprising.
Unity
God's word agrees with itself. A new teaching can't cancel an old one.
Evidence
Ask whether a claim matches what actually happened.
The Torah itself teaches the Unity tool. Deuteronomy 13 warns that even a prophet who performs a real sign or wonder must not be followed if he leads people away from God's commandments. Miracles alone don't prove a teaching true.
Pause and ponder
Think of something you believe. Could you explain why you believe it, using one of the four CLUE tools?
Five things to remember
- Judaism and Christianity share a Creator, the Hebrew Scriptures, and many moral teachings.
- Apologetics comes from the Greek apologia: a reasoned defense of what you believe.
- The Tanakh has 24 books. The Protestant Old Testament has the same text, divided into 39.
- The two faiths had clearly separated by the 300s CE, as Christian teachings such as the Trinity were formalized.
