When were the gospels written?

Of course, there is no way to know precisely when any of
the gospels of the Christian New Testament were written.  It is not as if they come with
copyright pages that we can check.  Instead, scholars have had to try to date the
gospels based on things such as events that they refer to.  Because of this, there is a
great deal of ambiguity as to when the gospels were written.  Church historians tend to
want to place the dates earlier whereas more secular scholars opt for later
dates.

The secular scholars believe that the gospels were
written between 65 AD (the earliest date assigned to Mark) and 110 (the latest date
given for John).  Church scholars argue for dates ranging from 50 to 100
AD.

Again, we cannot know for sure, but we have a good idea
as to the range of dates during which these books were being
written.
