Over time, the words got blurry. Here is what they actually mean.
The wordיְהוּדִי
Jewish, then and now
Hebrew Abraham's people→Israelite Jacob's family→Jew from Judah
ThenIn the Bible, being Jewish meant belonging to Israel's people, the family of Abraham, Isaac and Jacob, and worshiping the God of Israel. Life was built around the Torah, the Temple, the Sabbath, and waiting for the Messiah.
TodayBeing Jewish can mean faith, family, culture, or all three. Some Jewish people keep the faith closely. Many don't practice it, but still belong to the people. Traditional Jewish law passes it down through the mother, or through converting. Some Jewish movements count the father too.
Where it got blurryMany people grow up Jewish by family, even have a bar or bat mitzvah, and never get to read what the Prophets said about the Messiah. This page is a place to start.
The wordתּוֹרָה
Torah
"teaching"
The first five books of the Bible, written by Moses.
Where it got blurryIt sounds like a Jewish-only book. It is also the first five books of every Christian Bible.
The wordתַּנַ״ךְ
Tanakh
the Hebrew Bible
Three parts: Torah (teaching), Nevi'im (prophets), Ketuvim (writings). T-N-K.
Where it got blurryChristians call these same books the Old Testament.
The wordבְּרִית
Old Testament
"old covenant" · berit is Hebrew for covenant
The first part of the Christian Bible: the Hebrew Bible.
Where it got blurry"Old" can sound like "out of date." Jesus said, "I have not come to abolish them, but to fulfill them" (Matthew 5:17).
The wordבְּרִית חֲדָשָׁה
New Testament
"new covenant" · berit chadashah
The 27 books about Jesus and his first followers.
Where it got blurryIt sounds like another religion's book. Its very name comes from a Hebrew prophet: "a new covenant with the house of Israel and with the house of Judah" (Jeremiah 31:31).
The wordβιβλία
Bible
biblia · "the books"
A library on one shelf: 66 books in most Protestant Bibles.
Where it got blurryPeople think of two books. It's one library telling one story.
The wordמָשִׁיחַ
Messiah
Mashiach · "anointed one"
The King God promised, from David's family.
Where it got blurryIt's the same word as Christ, in another language.
The wordΧριστός
Christ
Christos · "anointed one"
The Greek word for Messiah.
Where it got blurryIt's a title, not a last name. "Jesus Christ" means "Jesus the Messiah."
The wordיֵשׁוּעַ
Jesus
Yeshua · "the LORD saves"
His Hebrew name. The same name as Joshua.
Where it got blurry"Jesus" sounds foreign to Jewish ears. His own family called him Yeshua.
The wordΧριστιανός
Christian
"a Messiah follower"
A follower of Jesus the Messiah. The name was first used in Antioch (Acts 11:26).
Where it got blurryIt sounds like the opposite of Jewish. The first followers were Jewish, and they believed Israel's Messiah had come.
