Any solution must account for the similarities and differences in content, order, and wording. The synoptic problem concerns how this interrelation came to pass and what the nature of this interrelationship is. Similarity in word choices and event placement shows an interrelationship. This problem concerns the literary relationships between and among the first three canonical gospels of Mark, Matthew, and Luke collectively known as the synoptic Gospels. The question of the relationship between the three is called the synoptic problem. The synoptic gospels often recount the same stories about Jesus, though sometimes with different and more or less detail, but mostly following the same sequence and to a large extent using the same words.
Christology is generally less concerned with the details of Jesus' life than it is with how the human and divine co-exist in one person. The fourth canonical gospel of John differs significantly from the synoptics in terms of Christology, which is the field of study within Christian theology which is concerned with the nature of Jesus the Christ, in particular, how the divine and human are related in his person. The Gospel according to John has a number of points of contact with the three synoptic Gospels but differs considerably from them in content and therefore not all Gospel synopses display the book of John. The term is also applied to apocryphal works of the 2nd century (e.g., The Gospel of Thomas). These first three books have been called the synoptic Gospels since the 18th century and are so called because they give similar accounts of the ministry of Jesus.
The term synoptic is derived from a combination of the Greek words συν (syn = together) and οψις (opsis = seeing) to indicate that the contents of these three Gospels can be viewed side-by-side, whether in a vertical parallel column synopsis, or a horizontal synoptic alignment. The Gospel parallels provided here also include the Gospel of John for comparison. The synoptic Gospels are the first three Gospels of the New Testament, Matthew, Mark and Luke and are considered as one unit. The Synoptic Gospel Parallels with John's Gospel
