Question: How many chapters are there in the gospel that is not considered one of the synoptic ones?

full_context: Document 1: Book of Revelation: Tradition links him to John the Apostle, but it is unlikely that the apostle could have lived into the most likely time for the book's composition, the reign of Domitian, and the author never states that he knew Jesus. All that is known is that this John was a Jewish Christian prophet, probably belonging to a group of such prophets, and was accepted as such by the congregations to whom he addresses his letter. His precise identity remains unknown, and modern scholarship commonly refers to him as John of Patmos.
Document 2: First Epistle of John: The First Epistle of John, often referred to as First John and written 1 John or I John, is the first of the Johannine epistles of the New Testament, and the fourth of the catholic epistles. It is attributed to John the Evangelist, traditionally thought to be the author of the Gospel of John and the other two Johannine epistles. This epistle was probably written in Ephesus in AD 95 -- 110. The work was written to counter docetism, which is the belief that Jesus did not come ``in the flesh '', but only as a spirit. It also defined how Christians are to discern true teachers: by their ethics, their proclamation of Jesus in the flesh, and by their love.
Document 3: John 1:1: The phrase ``the Word ''(a translation of the Greek word`` Logos'') is widely interpreted as referring to Jesus, as indicated in other verses later in the same chapter. This verse and others throughout Johannine literature connect the Christian understanding of Jesus to the philosophical idea of the Logos and the Hebrew Wisdom literature. They also set the stage for later understanding development of Trinitarian theology early in the post-biblical era.
Document 4: First Epistle of John: The First Epistle of John, often referred to as First John and written 1 John, is the first of the Johannine epistles of the New Testament, and the fourth of the catholic epistles. It is attributed to John the Evangelist, traditionally thought to be the author of the Gospel of John and the other two Johannine epistles. This epistle was probably written in Ephesus in AD 95 -- 110. The work was written to counter docetism, which is the belief that Jesus did not come ``in the flesh '', but only as a spirit. It also defined how Christians are to discern true teachers: by their ethics, their proclamation of Jesus in the flesh, and by their love.
Document 5: Codex Vercellensis: The Old Latin Codex Vercellensis Evangeliorum, preserved in the cathedral library, is believed to be the earliest manuscript of the Old Latin Gospels. Its standard designation is "Codex a" (or 3 in the Beuron system of numeration). The order of the gospels in this Codex is Matthew, John, Luke and Mark, which is also found in some other very old "Western" manuscripts, such as Codex Bezae. In its text of Matthew 3, before verse 16, there is a statement that a light suddenly shone when Jesus was baptized (Et cum baptizaretur, lumen ingens circumfulsit de aqua, ita ut timerent omnes qui advenerant). It contains the last twelve verses of the Gospel of Mark, but on a replacement-page. The original final pages after Mark 15:15 have been lost, and the replacement-page resumes mid-sentence in 16:7 and includes the text to the end of verse 20, but in the Vulgate version. Space considerations suggest that it is unlikely that the original, non-extant pages included verses 9-20, but this calculation (made by C. H. Turner in 1928) depends on unverifiable assumptions that only four pages have been lost, that the scribe did not accidentally skip any text, and that the person who made the replacement-page had access to the missing page that it replaced. However Turner did not explain why a scribe would replace only one of four pages. It is more probable that the replacement-page was removed from another manuscript than that it was made to insert in Codex Vercellensis. The text of Codex Vercellensis is related to the text of Codex Corbeiensis (ff), another Old Latin copy (in which Mk 16:9-20 is included).
Document 6: Synoptic Gospels: The gospels of Matthew, Mark, and Luke are referred to as the Synoptic Gospels because they include many of the same stories, often in a similar sequence and in similar wording. They stand in contrast to John, whose content is comparatively distinct. The term synoptic (Latin: synopticus; Greek: συνοπτικός, translit. synoptikós) comes via Latin from the Greek σύνοψις, synopsis, i.e. ``(a) seeing all together, synopsis ''; the sense of the word in English, the one specifically applied to these three gospels, of`` giving an account of the events from the same point of view or under the same general aspect'' is a modern one.
Document 7: United States Declaration of Independence: The declaration is not divided into formal sections; but it is often discussed as consisting of five parts: introduction, preamble, indictment of King George III, denunciation of the British people, and conclusion.
Document 8: Authorship of Luke–Acts: The authorship of the Gospel of Luke and the Acts of the Apostles, collectively known as Luke -- Acts, is an important issue for biblical exegetes who are attempting to produce critical scholarship on the origins of the New Testament. Traditionally, the text is believed to have been written by Luke the companion of Paul (named in Colossians 4: 14). However, the earliest manuscripts are anonymous, and the traditional view has been challenged by many modern scholars.
Document 9: Parable of the Sower: The Parable of the Sower (sometimes called the Parable of the Soils) is a parable of Jesus found in the three Synoptic Gospels in Matthew 13: 1 - 23, Mark 4: 1 - 20, and Luke 8: 1 - 15. In the story, a sower sows seed; some seed falls on the path (way side), on rocky ground and among thorns, and it is lost, but when it falls on good earth it grows, yielding thirty, sixty, and a hundredfold.
Document 10: Gospel of Mark: Mark probably dates from 66 -- 70 AD. It appears as the second New Testament gospel because it was traditionally thought to be an epitome (summary) of Matthew, but most scholars now regard it as the earliest written gospel. Some also reject the tradition which ascribes it to John Mark, the companion of the apostle Peter, and regard it as the work of an unknown author working with various sources including collections of miracle stories, controversy stories, parables, and a passion narrative.
Document 11: Third Epistle of John: The Third Epistle of John, often referred to as Third John and written 3 John or III John, is the antepenultimate book of the New Testament and attributed to John the Evangelist, traditionally thought to be the author of the Gospel of John and the other two epistles of John. The Third Epistle of John is a private letter composed to a man named Gaius, recommending to him a group of Christians led by Demetrius, which had come to preach the gospel in the area where Gaius lived. The purpose of the letter is to encourage and strengthen Gaius, and to warn him against Diotrephes, who refuses to cooperate with the author of the letter.
Document 12: Gospel: The four gospels of the New Testament -- Matthew, Mark, Luke and John -- are almost our only source of information on Jesus, and thus occupy a uniquely important place in Christianity. They were all written in the period between c. 70 AD and the end of the 1st century, by anonymous authors, and stand at the end of a process of oral and written tradition that began on, or even before, the death of Jesus.
Document 13: Crucifixion of Jesus: Modern biblical scholarship treats the account in the synoptic gospels as a literary creation by the author of the Mark Gospel, amended in the Luke and Matthew accounts, intended to heighten the importance of what they saw as a theologically significant event, and not intended to be taken literally. This image of darkness over the land would have been understood by ancient readers, a typical element in the description of the death of kings and other major figures by writers such as Philo, Dio Cassius, Virgil, Plutarch and Josephus. Géza Vermes describes the darkness account as typical of "Jewish eschatological imagery of the day of the Lord", and says that those interpreting it as a datable eclipse are "barking up the wrong tree".
Document 14: Gospel of John: The Gospel of John can be divided into four sections: a prologue (1: 1 -- 18), a Book of Signs (1: 19 -- 12: 50), a Book of Glory (13: 1 -- 20: 31), and an epilogue (21). The structure is highly schematic: there are seven ``signs ''culminating in the raising of Lazarus (foreshadowing the resurrection of Jesus), and seven`` I am'' sayings and discourses, culminating in Thomas's proclamation of Jesus as ``my lord and my God ''-- the same title (dominus et deus) claimed by Roman Emperor Domitian.
Document 15: Seven churches of Asia: In an early part of the Revelation, on the Greek island of Patmos, Jesus Christ instructs John of Patmos to: ``Write on a scroll what you see and send it to the seven churches: to Ephesus, and to Smyrna, and to Pergamum, and to Thyatira, and to Sardis, and to Philadelphia, and to Laodicea.
