It would be an aid to modern study if we could be certain {15} when and where the four Gospels were put together in one canon. In the 4th and 5th centuries it was believed by some Christians that the collection had been made at Ephesus by St. John himself, and that he had prefixed the names of the writers to the Gospels when he published his own Gospel. It is at present impossible to discover how far this supposed fact is legendary or not, but modern criticism has done something to corroborate the idea that the Gospels were really collected first in Asia Minor, and if St. John did not make the collection himself, it was probably made by his disciples soon after his death. [Sidenote: Their Diversity.] If we compare the four Gospels together, it is as plain as daylight that there is a marked difference between the first three Gospels on the one hand and the fourth Gospel on the other hand. The first three Gospels are usually called the _Synoptic Gospels_, because they give us one _synopsis_ or common view of our Lord's work. To a great extent they record the same events and the same discourses, and in many passages they express themselves in almost identical words. The account which they give of our Lord's work is mostly confined to His ministry in Galilee, the birthplace of our religion, and it includes only one visit to Jerusalem. But St. John's Gospel differs widely in language from the other Gospels, and also gives an account of no less than five visits to Jerusalem, and chiefly describes the scenes connected with our Lord's ministry in Judaea. Whereas our first three Gospels can be appropriately printed in three parallel columns, the greater part of St. John's Gospel cannot be appropriately placed by the side of the other three. Another most important difference is that St. John's Gospel is marked by a tone and teaching which are seldom to be found in the Synoptic Gospels. The difference was well expressed by Clement of Alexandria, who calls the Synoptic Gospels _bodily_ and St. John's Gospel _spiritual_; and by Theodore of Mopsuestia, who says that St. John declared that "doubtless it was not right to omit {16} the facts told with regard to the sojourn of Christ in the flesh, but neither was it right to omit the words relating to His Divinity." For the Synoptic Gospels relate the outward events connected with our Lord's ministry, while St. John records the discourses and works which reveal our Lord's heavenly origin and divine authority. Again, the Synoptic Gospels report Christ's addresses to simple Galilean people, addresses consisting largely of _parables_; while St. John reports discourses, frequently expressed in the language of _allegory_, and uttered to the Jews of Jerusalem or to His own intimate disciples.
