It is stated in the gospels that the Last Supper was the Passover meal, though certain discrepancies between the accounts given in the Synoptics and in John render this doubtful.
And this was true in regard to the two which, from a comparison of his Gospel with the other two Synoptics, we know that he did use.
A moderately liberal theologian, he became best known as a New Testament critic and exegete, being the author of the Commentary on the Synoptics (1889; 3rd ed., 1901), the Johannine books (1890; 2nd ed., 1893), and the Acts of the Apostles (1901), in the series Handkommentar zum Neuen Testament.
He speaks of a Christian collection of writings, and knew and used the gospels, but was influenced less by the fourth than by the Synoptics.
(i.) There are traces of earlier discussions about the Gospels, both in disparagement of the Synoptics as compared with St John, and in criticism of the latter as differing from the former.
