"Wasn't [the New Testament] written like 300 years after Jesus?"
No, the New Testament wasn't written 300 years after Jesus.
You may be referring to 325 AD, when the Council of Nicaea officially
recognized the New Testament as having been written by God. By then, Christians had been
reading the New Testament as God's Word for 2 centuries.
So when was the New Testament written?
Please pay close attention to the dates below to decipher when the New Testament was
written:
Acts, the fifth book in the New Testament, is a methodical account of the early church
written by a doctor named Luke when he was the assistant to and the note taker for
the Apostle Paul.
62 AD was when Paul was martyred in Rome. 64 AD was when Emperor Nero burnt Rome
and blamed the fire on Christians to launch the Roman persecution of Christians.
70 AD was when the future Emperor Titus sacked Jerusalem.
Acts ends with Paul having just completed his 2-year
imprisonment in Rome but without mentioning his martyrdom. Acts also does not
mention the start of the Roman persecution of Christians or the destruction of
Jerusalem, both monumental milestones in Christian history. This indicates that Acts was writte
n around 62 AD.
Luke begins Acts with:
"The former account I made, O Theophilus, of all that
Jesus began both to do and teach..." (
Acts 1:1)
The
“former account” Luke referred to was what we call
today the Gospel of Luke, which was also writte
n by Luke to this man named Theophilus:
"Inasmuch as many
have taken in hand to set in order a narrative of those things which have
been fulfilled among us, just as those who from the beginning were
eyewitnesses and ministers of the word delivered them to us, it seemed good
to me also, having had perfect understanding of all things from the very
first, to write to you an orderly account, most excellent
Theophilus, that
you may know the certainty of those things in which you were instructed."
(
Luke 1:1-4)
The delivered eyewitness accounts Luke mentions above are the
Gospel of Matthew, writte
n by one of Jesus' 12 Apostles, and the Gospel
of Mark, writte
n by the note taker for Apostle Peter.
Estimating 3-5 years between Acts and Luke, and another 3-5 years
between Luke and Matthew & Mark dates three of the four Gospels to 52-59 AD,
which is only 2 decades after
Jesus'
ascension.
Some of the other Ne
w Testamen
t books were writte
n before and some after
these Gospels, but all were writ
ten by eyewitnesses of Jesus or their note takers, and read by people who were also eyewitnesses and could validate
their details.
