The Sermon on the Mount announces the awakening of the true prophetic spirit in Israel after a sleep of five hundred years.

An intolerant nationalism

A sinister phase of the orthodox religious-ethical system of the postexilic age was its narrow, intolerant nationalism. To be an enemy of Israel was what was believed to constitute wickedness, and to excite the wrath of Yahweh, just as later in the ethics of certain systems of Christian theology the unbeliever or pagan, merely because of his unbelief or paganism, was regarded as wicked and as deserving of eternal punishment. In psalms which date from this period these enemies of Yahweh are cursed with a fierce hatred which spares not even the children, but pronounces happy him who shall take up and dash the little ones against the stones.[413] Nowhere in history do we meet with a more fanatically intolerant nationalism.

The relation of the synagogue to the moral evolution

It was only a comparatively small part of the Jewish nation whose home was the city of Jerusalem in the later postexilic period. The Israelite community was now widely scattered in the cities of the East and the West. One important outcome of this, in its bearings upon the moral life of Israel and of the nations that were to receive ethical instruction from her, was the establishment of the synagogue.[414] For the Deuteronomic code had made religion to be something connected with the Temple, something separate and apart from true morality, whose root is in human relationships. Now the Dispersion, tearing the Israelites away from the Temple, tended to bring into prominence those religious exercises and those duties which had nothing to do with the Temple service. This was favorable to the religion and morality of the prophets, as opposed to the religion and morality of the priests. The services of the synagogue took the place of the ceremonies and sacrifices of the Temple.[415] These services consisted in the reading and translation of a portion of the Scriptures with comments thereupon.[416] This meant the incoming of a new and powerful agency in the promotion not only of the religious but also of the moral education of humanity, for this custom “was the origin of the homily and sermon.”[417] The synagogue was the prototype and precursor of the Christian basilica and the Puritan meetinghouse.

The new doctrine of immortality: its ethical import

The reëstablishment of the Law we have pronounced the chief ethical fact in the history of Judaism after the return from the Babylonian Captivity. And this is true if it is the history of the Jews alone that we have in mind; but regarding the moral evolution in the world at large there is another fact belonging to this period of even greater importance. This was the incoming of the doctrine of immortality.[418]

We have seen that from the first the Hebrews, like the Babylonians, held a belief in a sort of shadowy existence after death;[419] but of a belief in personal immortality in our sense of the word, of a life of rewards and punishments beyond the grave, there is no certain trace in Hebrew literature until about the third or second century B.C.[420]

Different influences had concurred to create this new conception of the hereafter and to secure for it by the end of the Greek period a wide acceptance. First, there was what has been called the subjective sense of fellowship with God. During this period of Israelite history there was engendered in select souls a passionate outreaching after divine companionship. This feeling is revealed in many a postexilic psalm, as where the psalmist exclaims, “For thou wilt not leave my soul to Sheol; neither wilt thou suffer thine holy one [beloved] to see corruption.”[421] This was the divination of love like that of the old mystic who exclaimed, “O God, if I should die, Thou couldst not live.”[422] It was such filial love and trust as this, which found its divinest expression in the life of “the Sublime Mystic of Galilee,” that created in many a devout soul in Israel that larger hope which gave birth to the doctrine of personal immortality.

But while it was probably deep religious feeling, the soul’s recognition of its sonship to God, that called into existence the idea of personal immortality, it was the ethical necessity created by a profound faith in God’s absolute justice, an irrefragable conviction that under the moral government of the world well-doing will be rewarded and evildoing punished, that gained for the doctrine its wide acceptance. That good men should be afflicted and wicked men should enjoy prosperity, has in all ages of reflection caused questionings and murmurings. But this ethical problem filled with peculiar unrest the souls of the Israelites, first, because more than any other people they felt the need of a just God; and second, because of their lack of belief in a future life of rewards and punishments in which the wrongs and inequalities of this life might be righted. Hence the many different solutions of the problem which they thought out, and through which they sought to justify the ways of God to man. So long, however, as life practically ended at the grave, the problem remained insolvable. But the doctrine of another existence in which the righteous man should receive compensation for his sufferings here, and the evil man just retribution for his deeds, offered a reasonable solution of the problem that had so troubled the conscience of Israel. It was this undoubtedly that caused the teaching to gain popular currency.
