C
hristianity takes its
name from the Greek word
christós, a translation of
the Hebrew word for messiah, or
anointed one. This title was given
to Jesus by a Jewish sect who
considered him to be the Messiah
—the savior prophesied in the
Tanakh, the Hebrew Bible—and
the Son of God in human form.
Christians believe that Jesus’s
arrival on earth heralded a New
Covenant or New Testament
with God that followed the Old
Testament covenants between
God and the Jewish people.
The main beliefs of Christianity
are based on the life and teachings
of Jesus as recorded by his
followers in the 1st century CE
in the Gospels (meaning “good
news”) and the Epistles (or letters)
of the New Testament.
Christians give great significance
to the story of Jesus’s crucifixion,
resurrection, and ascension to
heaven. It is the central belief of
Christianity that Jesus suffered,
died, and was buried, before being
resurrected from the dead—in
order to grant salvation to those
who believe in him—and that
he then ascended to heaven
to rule alongside God the Father.
Implicit in this belief is the
acceptance that Jesus was, as the
Son of God, God incarnate, both
human and divine, and not merely
a prophet. This led to the concept
of the Trinity, that the one God
exists in three distinct forms—the
Father, the Son, and the Holy Spirit.
The life of Jesus also provides
a framework for the rituals of
Christian worship, the most
important of which are known as
sacraments. Especially significant
are the sacraments of baptism and
the Eucharist—the taking of bread
and wine, as Jesus instructed his
followers at the Last Supper. Others
include confirmation, holy orders
(the ordination of ministers),
confession, the anointing of the
sick, and matrimony—although
not all of these are accepted by
every Christian denomination.
Persecution to adoption
From its beginnings in Roman
Judea to its status as the religion
with most adherents in the world
today, Christianity has shaped
the culture of much of Western
civilization. The early Christians
were persecuted by both Jewish
authorities and the Roman Empire,
and many were put to death.
Nevertheless, the faith persisted
