Apostasy from the Mosaic and prophetic religion was naturally accompanied by social corruption. It has recently been maintained that the universal instinct which inclines man to be religious is not necessarily moral, and that it is the distinguishing note of the true faith, or of religion proper, that it enlists this somewhat neutral instinct in the cause of a pure morality. The Phœnician and Syrian cults, with which Israel was most closely in contact, sufficiently illustrated the combination of fanatical religious feeling with gross impurity. On the other hand, the teaching of Revelation to Israel consistently inculcated a high morality and an unselfish benevolence. The prophets vehemently affirmed the worthlessness of religious observances by men who oppressed the poor and helpless. Apostasy from Jehovah to Baal and Moloch involved the same moral lapse as a change from loyal service of Christ to a pietistic antinomianism. Widespread apostasy meant general social corruption. The most insidious form of apostasy was that specially denounced by Jeremiah, in which the authority of Jehovah was more or less explicitly claimed for practices and principles which defied His law. The Reformer loves a clear issue, and it was more difficult to come to close quarters with the enemy when both sides professed to be fighting in the King's name. Moreover the syncretism which still recognised Jehovah was able without any violent revolution to control the established institutions and orders of the state--palace and temple, king and princes, priests and prophets. For a moment the Reformation of Josiah, and the covenant entered into by king and people to observe the law as laid down in the newly discovered Book of Deuteronomy, seemed to have raised Judah from its low estate. But the defeat and death of Josiah and the deposition of Jehoahaz followed to discredit Jeremiah and his friends. In the consequent reaction it seemed as if the religion of Jehovah and the life of His people had become hopelessly corrupt.
We are too much accustomed to think of the idolatry of Israel as something openly and avowedly distinct from and opposed to the worship of Jehovah. Modern Christians often suppose that the true worshipper and the ancient idolater were as contrasted as a pious Englishman and a devotee of one of the hideous images seen on missionary platforms; or, at any rate, that they were as easily distinguishable as a native Indian evangelist from his unconverted fellow-countrymen.
This mistake deprives us of the most instructive lessons to be derived from the record. The sin which Jeremiah denounced is by no means outside Christian experience; it is much nearer to us than conversion to Buddhism--it is possible to the Church in every stage of its history. The missionary finds that the lives of his converts continually threaten to revert to a nominal profession which cloaks the immorality and superstition of their old heathenism. The Church of the Roman Empire gave the sanction of Christ's name and authority to many of the most unchristian features of Judaism and Paganism; once more the rites of strange gods were associated with the worship of Jehovah, and a new Queen of Heaven was honoured with unlimited incense. The Reformed Churches in their turn, after the first "kindness of their youth," the first "love of their espousals," have often fallen into the very abuses against which their great leaders protested; they have given way to the ritualistic spirit, have put the Church in the place of Christ, and have claimed for human formulæ the authority that can only belong to the inspired Word of God. They have immolated their victims to the Baals and Molochs of creeds and confessions, and thought that they were doing honour to Jehovah thereby.
Moreover we have still to contend like Jeremiah with the continual struggle of corrupt human nature to indulge in the luxury of religious sentiment and emotion without submitting to the moral demands of Christ. The Church suffers far less by losing the allegiance of the lapsed masses than it does by those who associate with the service of Christ those malignant and selfish vices which are often canonised as Respectability and Convention.
