Jeremiah 10:3

8. The spirits of good or evil cannot dwell within material symbols of clay, wood, or metal; idols are nothing more than the material of which they are made.

The belief that water or precious metals beneath the earth’s surface can be detected by a wooden divining rod is a relic of the ancient tree cults. The Maypole, the Christmas tree, and the superstitious practice of rapping on wood perpetuate certain of the ancient customs of tree worship and the later-day tree cults.

Ideas about tree spirits varied greatly among different tribes and races. Some trees were indwelt by kindly spirits; others harbored the deceptive and cruel. The Finns believed that most trees were occupied by kind spirits. The Swiss long mistrusted the trees, believing they contained tricky spirits. The inhabitants of India and eastern Russia regard the tree spirits as being cruel. The Patagonians still worship trees, as did the early Semites. Long after the Hebrews ceased tree worship, they continued to venerate their various deities in the groves. Except in China, there once existed a universal cult of the tree of life.

Having worshiped everything else on the face of the earth and in the heavens above, man has not hesitated to honor himself with such adoration. The simple-minded savage makes no clear distinction between beasts, men, and gods.

The cults of tree worship are among the oldest religious groups. All early marriages were held under the trees, and when women desired children, they would sometimes be found out in the forest affectionately embracing a sturdy oak. Many plants and trees were venerated because of their real or fancied medicinal powers. The savage believed that all chemical effects were due to the direct activity of supernatural forces.

Religion clings to the mores; that which was is ancient and supposedly sacred. For this reason and no other, stone implements persisted long into the age of bronze and iron. This statement is of record: “And if you will make me an altar of stone, you shall not build it of hewn stone, for, if you use your tools in making it, you have polluted it.” Even today, the Hindus kindle their altar fires by using a primitive fire drill. In the course of evolutionary religion, novelty has always been regarded as sacrilege. The sacrament must consist, not of new and manufactured food, but of the most primitive of viands: “The flesh roasted with fire and unleavened bread served with bitter herbs.” All types of social usage and even legal procedures cling to the old forms.

Micah denounced “the rulers who judge for reward and the priests who teach for hire and the prophets who divine for money.” He taught of a day of freedom from superstition and priestcraft, saying: “But every man shall sit under his own vine, and no one shall make him afraid, for all people will live, each one according to his understanding of God.”

3. Vanity — longing to display one’s property accumulations. Extra clothing was one of the first badges of distinction. Collection vanity early appealed to the pride of man.

But these customs are not an unmitigated evil; their evolution should continue. It is nearly fatal to the continuance of civilization to undertake their wholesale modification by radical revolution. Custom has been the thread of continuity which has held civilization together. The path of human history is strewn with the remnants of discarded customs and obsolete social practices; but no civilization has endured which abandoned its mores except for the adoption of better and more fit customs.

Tree fetishes were a later development, but among some tribes the persistence of nature worship led to belief in charms indwelt by some sort of nature spirit. When plants and fruits became fetishes, they were taboo as food. The apple was among the first to fall into this category; it was never eaten by the Levantine peoples.
