In the ministry subsequent to the confession of Peter the self-disclosures of Jesus became more frequent and clear. His predictions of his approaching death were at the time the greatest difficulty to his disciples; when considered in their significance for his own life, however, they prove that his conviction of his Messiahship was as independent of current and inherited ideas as was his teaching concerning the kingdom. When he came to see that death was the inevitable issue of his work, he at once discovered in it a divine necessity; it does not seem to have shaken in the least his certainty that he was the Messiah. Associated with this conception of his death is the conviction which appears in all the later teachings, that in rejecting him his people were pronouncing their own doom. Because she would not accept him as her deliverer, Jerusalem's "house was left unto her desolate" (Luke xiii. 35). His sense of his supreme significance appears most clearly in some of the later parables, such as The Marriage of the King's Son (Matt. xxii. 1-14) and The Wicked Husbandmen (Matt. xxi. 33-44), which definitely connect the condemnation of the chosen people with their rejection of God's Son. Two other sayings in the first three gospels express the personal claim of Jesus in the most exalted form,--his declaration on the return of the seventy: "All things have been delivered unto me of my Father, and no man knoweth who the Son is save the Father, and who the Father is save the Son, and he to whomsoever the Son willeth to reveal him" (Luke x. 22; Matt. xi. 27); and his confession of the limits of his own knowledge: "But of that day and hour knoweth no one, not even the angels in heaven, neither the Son, but the Father" (Mark xiii. 32). The confession of ignorance, by the position given to the Son in the climax which denied that any save the Father had a knowledge of the time of the end, is quite as extraordinary as the claim to sole qualification to reveal the Father.
The similarity of these last two sayings to the discourses in the fourth gospel has often been remarked; the likeness is particularly close between them and the claims of Jesus recorded in the fifth chapter of John. It is interesting to note that in the incident which introduces the discourse in that chapter Jesus shows that he preferred, after healing the man at the pool, to avoid the attention of the multitudes, precisely as in Galilee he sought to check too great popular excitement by withdrawing from Capernaum after his first ministry there (Mark i. 35-39), and enjoining silence on the leper who had been healed by him (Mark ii. 44). When, however, he found himself opposed by the criticism of the Pharisees he spoke with unhesitating self-assertion and exalted personal claim, even as he did in like situations in Galilee. During his earlier ministry in Judea he had not shown this reserve. The cleansing of the temple, although it was no more than any prophet sure of his divine commission would have done, was a bold challenge to the people to consider who he was who ventured thus to criticise the priestly administration of God's house. In his subsequent dealings with Nicodemus and the Samaritan woman Jesus manifested a like readiness to draw attention to himself. From the time of the feeding of the multitudes all four of the gospels represent him as asserting his claims, with this difference, however, that in John it is the rule rather than the exception to find sayings similar to the two in which the self-assertion in the other gospels reaches its highest expression. Although the method of Jesus varied at different times and in different localities, yet it is evident that he stood before the people from the first with the consciousness that he had the right to claim their allegiance as no one of the prophets who preceded him would have been bold to do.
During the course of his ministry Jesus used of himself, or suffered others to use with reference to him, many of the titles by which his people were accustomed to refer to the Messiah. Thus he was named "the Messiah" (Mark viii. 29; xiv. 61; John iv. 26); "the King of the Jews" (Mark xv. 2; John i. 49; xviii. 33, 36, 37); "the Son of David" (Mark x. 47, 48; Matt. xv. 22; xxi. 9, 15); "the Holy One of God" (John vi. 69; compare Mark i. 24); "the Prophet" (John vi. 14; vii. 40). It is evident that none of these titles was common; they represent, rather, the bold venture of more or less intelligent faith on the part of men who were impressed by him. There are two names, however, that are more significant of Jesus' thought about himself,--"the Son of God" and "the Son of Man."
The latter of these titles is unique in the use Jesus made of it. Excepting Stephen's speech (Acts vii. 56), it is found in the New Testament only in the sayings of Jesus, and its precise significance is still a subject of learned debate. The expression is found in the Old Testament as a poetical equivalent for Man, usually with emphasis on human frailty (Ps. viii. 4; Num. xxiii. 19; Isa. li. 12), though sometimes it signifies special dignity (Ps. lxxx. 17). Ezekiel was regularly addressed in his visions as Son of Man (Ezek. ii. 1 and often; see also Dan. viii. 17), probably in contrast with the divine majesty.
In one of Daniel's visions (vii. 1-14) the world-kingdoms which had oppressed God's people and were to be destroyed were symbolized by beasts that came up out of the sea,--a winged lion, a bear, a four-headed winged leopard, and a terrible ten-horned beast; in contrast with these the kingdom of the saints of the Most High was represented by "one like unto a son of man," who came with the clouds of heaven (vii. 13, 14). Here the language is obviously poetic, and is used to suggest the unapproachable superiority of the kingdom of heaven to the kingdoms of the world. The expression "one like unto a son of man" is equivalent, therefore, to "one resembling mankind." The vision in Daniel had great influence over the author of the so-called Similitudes of Enoch (Book of Enoch, chapters xxxvii. to lxxi.). He, however, personified the "one like unto a son of man," and gave the title "the Son of Man" to the heavenly man who will come at the end of all things, seated on God's throne, to judge the world. This author used also the titles "the Elect One" and "the Righteous One" (or "the Holy One of God"), but "the Son of Man" is the prevalent name for the Messiah in these Similitudes.
The facts thus stated do not account for Jesus' use of the expression. Many of his sayings undoubtedly suggest a development of the Daniel vision resembling that in the Similitudes. This does not prove that Jesus or his disciples had read these writings, though it does suggest the possibility that they knew them. It is probable, however, that the apocalypses gave formulated expression to thoughts that were more widely current than those writings ever came to be. The likeness between the language of Jesus and that found in the Similitudes may therefore prove no more than that the Daniel vision was more or less commonly interpreted of a personal Messiah in Jesus' day.
Much of the use of the title by Jesus, however, is completely foreign to the ideas suggested by Enoch and Daniel. Besides apocalyptic sayings like those in Enoch (Mark viii. 38 and often), the name occurs in predictions of his sufferings and death (Mark viii. 31 and often), and in claims to extraordinary if not essentially divine authority (Mark ii. 10, 28 and parallels); it is also used sometimes simply as an emphatic "I" (Matt. xi. 19 and often). Whatever relation Jesus bore to the Enoch writings, therefore, the name "the Son of Man" as he used it was his own creation.
Students of Aramaic have in recent years asserted that it was not customary in the dialect which Jesus spoke to make distinction between "the son of man" and "man," since the expression commonly used for "man" would be literally translated "son of man." It is asserted, moreover, that if our gospels be read substituting "man" for "the Son of Man" wherever it appears, it will be found that many supposed Messianic claims become general statements of Jesus' conception of the high prerogatives of man, while in other places the name stands simply as an emphatic substitute for the personal pronoun. Thus, for instance, Jesus is found to assert that authority on earth to forgive sins belongs to man (Mark ii. 10), and, toward the end of his course, to have taught simply that he himself must meet with suffering (Mark viii. 31), and will come on the clouds to judge the world (Mark viii. 38). The proportion of cases in which the general reference is possible is, however, very small; and even if the equivalence of "man" and "son of man" should be established, most of the statements of Jesus in which our gospels use the latter expression exhibit a conception of himself which challenges attention, transcending that which would be tolerated in any other man. The debate concerning the usage in the language spoken by Jesus is not yet closed, however, and Dr. Gustaf Dalman (WJ I. 191-197) has recently argued that the equivalence of the two expressions holds only in poetic passages, precisely as it does in Hebrew, and that our gospels represent correctly a distinction observed by Jesus when they report him, for instance, as saying in one sentence, "the Sabbath was made for man" (Mark ii. 27), and in the next, "the Son of Man is lord even of the Sabbath." The antecedent probability is so great that the dialect of Jesus' time would be capable of expressing a distinction found in the Hebrew of the Old Testament and in the Syriac of the second-century version of the New Testament, that Dalman's opinion carries much weight.
Many of those who look for a distinct significance in the title "the Son of Man," find in it a claim by Jesus to be the ideal or typical man, in whom humanity has found its highest expression. It thus stands sharply in contrast with "the Son of God," which is held to express his claim to divinity. So understood, the titles represent truth early recognized by the church in its thought about its Lord. Yet it must be acknowledged that the conception "the ideal man" is too Hellenic to have been at home in the thought of those to whom Jesus addressed his teaching. If the phrase suggested anything more to his hearers than the human frailty or the human dignity of him who bore it, it probably had a Messianic meaning like that found in the Similitudes of Enoch. A hint of this understanding of the name appears in the perplexed question reported in John (xii. 34): "We have heard out of the law that the Messiah abideth forever; and how sayest thou, The Son of Man must be lifted up? who is this Son of Man?" Here the difficulty arose because the people identified the Son of Man with the Messiah, yet could not conceive how such a Messiah could die. In fact, if the conception of the Son of Man which is found in Enoch had obtained any general currency among the people, either from that book or independently of it, it was so foreign to the earthly condition and manner of life of the Galilean prophet, that it would not have occurred to his hearers to treat his use of the title as a Messianic claim until after that claim had been published in some other and more definite form. Their Son of Man was to come with the clouds of heaven, seated on God's throne, to execute judgment on all sinners and apostates; the Nazarene fulfilled none of these conditions. The name, as used by Jesus, was probably always an enigma to the people, at least until he openly declared its Messianic significance in his reply to the high-priest's question at his trial (Mark xiv. 62), and gave the council the ground it desired for a charge of blasphemy against him.
What did this title signify to Jesus? His use of it alone can furnish answer, and in this the variety is so great that it causes perplexity. "The Son of Man came eating and drinking" is his description of his own life in contrast with John the Baptist (Matt. xi. 18, 19). "The Son of Man hath not where to lay his head" was his reply to one over-zealous follower (Matt. viii. 20). Unseemly rivalry among his disciples was rebuked by the reminder that "even the Son of Man came not to be ministered unto but to minister" (Mark x. 42-45). When it became needful to prepare the disciples for his approaching death he taught them that "the Son of Man must suffer many things ... and be killed, and after three days rise again" (Mark viii. 31). On the other hand, the paralytic's cure was made to demonstrate that "the Son of Man hath authority upon the earth to forgive sins" (Mark ii. 10). Similarly it is the Son of Man who after his exaltation shall come "in the glory of his Father with the holy angels" (Mark viii. 38). In these typical cases the title expresses Jesus' consciousness of heavenly authority as well as self-sacrificing ministry, of coming exaltation as well as present lowliness; and the suffering and death which were the common lot of other sons of men were appointed for this Son of Man by a divine necessity. The name is, therefore, more than a substitute for the personal pronoun; it expresses Jesus' consciousness of a mission that set him apart from the rest of men.
