48. So long a ministry as three years presents some difficulties, for all that is told us in the four gospels would cover but a small fraction of this time. John’s statement (xx. 30) that he omitted many things from Jesus’ life in making his book is evidently true of all the evangelists, and long gaps, such as are evident in the fourth gospel, must be assumed in the other three. Recalling the character of the gospels as pictures of Jesus rather than narratives of his life, we may easily acknowledge the incompleteness of our record of the three years of ministry, and wonder the more at the vividness of impression produced with such economy of material. This meagreness of material is not decisive for the shorter rather than the longer ministry, for it is evident that to effect such a change in conviction and feeling as Jesus wrought in the minds of the ardent Galileans who were his disciples, required time. Three years are better suited to effect this change than two.
49. Closely related to the question of the length of Jesus’ ministry is another: Can definite dates be given for the chief events in his life? For the year of the opening of his public activity the gospels furnish two independent testimonies: the remark of the Jews on the occasion of Jesus’ first visit to Jerusalem, “Forty and six years was this temple in building” (John ii. 20), and Luke’s careful dating of the appearance of John the Baptist, “in the fifteenth year of Tiberius Caesar” (iii. 1, 2). John ii. 20 leads to the conclusion that the first Passover fell in the spring of A.D. 26 or 27, since we learn from Josephus (Ant. xv. 11. 1) that Herod began to rebuild the temple in the eighteenth year of his reign, which closed in the spring of B.C. 19. Luke iii. 1 gives a
