In the original manuscripts of the Gospels, there were no chapter-divisions. Today in English Bibles, Matthew has 28 chapters, Mark has 16 chapters, Luke has 24 chapters, and John has 21 chapters. In many Greek Gospels-manuscripts, the division is very different: Matthew has 68 chapters; Mark has 48, Luke has 83, and John has 18 or 19. Often, before each Gospel, copyists wrote a list of the chapters’ numbers and titles (titloi), which served as a table of contents. Within the text of the Gospel itself, on the page where a chapter began, a copyist wrote the chapter’s number and name at the top of the page; these are the kephalaia (headings), usually written in red. When more than one chapter began on the same page, copyists would write the second kephalon in the lower margin.

| Most of the Kephalaia-list for the Gospel of Mark in the medieval Exoteicho Gospels (2396). | 
          There are some aspects of the kephalaia which one might not expect.  For example, each Gospel does not begin with
chapter 1.  The opening portion of each
Gospel was treated as a preface, and did not receive a chapter-number.  Thus the first chapter in Matthew begins at 2:1, and the first chapter in Mark begins at 1:23 .  Also, the ancient chapters vary wildly in
size.  Chapter 40 of Luke consists of
only two verses, while some of the chapters in John include more than one of
our modern chapters.  Almost all of the
chapters begin with the word περι, which means about, and typically this word is abbreviated in the list of titloi and in the kephalaia as πε, sometimes with one letter above the other.
          Also, most of the chapters in John are relatively huge
compared to most of the chapters in Matthew, Mark, and Luke.  It may be that the chapter-divisions in the
Synoptic Gospels were prepared first, and that at least part of their purpose
was to give readers the means to easily locate each Gospel’s account of some of
the same events.  This would explain why
many of the chapter-titles in Matthew are repeated in Mark and/or Luke.  (For example, kephalaia 31, 32, 33, 34, and 35 of Matthew are the same as kephalaia 21, 22, 34, 25, and 26 of
Mark.)  The contents of John were, for
the most part, not divided into smaller portions because for long stretches, there are no close parallels overlapping the text, until the reader comes to a point in the narrative
where the contents of the other Gospels overlapped.

          The chapters do not always begin at exactly the same place,
and the chapter-titles sometimes vary in detail.  (Sometimes, when manuscripts share variations
in the chapter-titles, they also share variations in the Gospels-text.  The kephalaia in members of the family-13 group of manuscripts are particularly distinct.)  The longer the heading, the more likely it was
to be shortened by copyists.  Perhaps the
most drastic difference in titloi-lists occurs in lists of the ancient chapters of the Gospel
of John; in some manuscripts the story of the adulteress constitutes a chapter-unit.
          The following list (compiled with information from Greg Goswell, Reuben Swanson, and other sources) gives the number (in normal
numerals and in Greek characters), location, and name of each ancient chapter
in the Gospels.  (In the 27th edition of the Nestle-Aland Novum
Testamentum Graece, the beginnings of the ancient chapters are represented
by italicized numbers in the inner margin.)
