Eureka!

It is a simple Greek word, only six letters long. But for a generation of treasure seekers in the late 1840s, it became a life slogan. Meaning “I have found it!” in English, the term purportedly comes from Archimedes, the Greek mathematician who cried out “Eureka! Eureka!” when he determined how much gold was in King Hiero’s crown. Yet, for James Marshall (who discovered gold at Sutter’s Mill in 1848) and many of his contemporaries, the term took on new meaning. For them, “eureka” meant instant riches, early retirement, and a life of carefree ease. It’s no wonder California (the “Golden State”) includes this term on its official seal, along with the picture of a zealous gold miner.

News of Marshall’s discovery spread quickly throughout the nation. By 1850 over 75,000 hopefuls had traveled to California by land, and another 40,000 by sea. Whether by wagon or by boat, the journey was an arduous one, as adventurers left friends and family behind in search of vast fortunes. Even when they finally arrived in San Francisco, the closest goldfields were still 150 miles away. Undaunted nonetheless, many of the forty-niners set up mining camps and started to dig.

As they traveled out to their various destinations, prospectors quickly learned that not everything that looked like gold actually was. Riverbeds and rock quarries could be full of golden specks, and yet entirely worthless. This “fool’s gold” was iron pyrite, and miners had to be able to distinguish it from the real thing. Their very livelihood depended on it.

Experienced miners could usually distinguish pyrite from gold simply by looking at it. But in some cases the distinction was not quite so clear. So they developed tests to discern what was genuine from what wasn’t. One test involved biting the rock in question. Real gold is softer than the human tooth, while fool’s gold is harder. A broken tooth meant that a prospector needed to keep digging. A second test involved scraping the rock on a piece of white stone, such as ceramic. True gold leaves a yellow streak, while the residue left by fool’s gold is greenish-black. In either case, a miner relied on tests to authenticate his finds.

Doctrinally speaking, today’s church is in a similar position to the California gold rushers of 1850. Spiritual riches are promised at every turn. New programs, new philosophies, new parachurch ministries—each glitters a little bit more than the last, promising better results and bigger returns. But, as was true in the mid-1800s, just because it glitters doesn’t mean it’s good. Christians need to be equally wary of “fool’s gold.” We must not accept new trends (or old traditions) without first testing them to see if they meet with God’s approval. If they fail the test, we should discard them and warn others also. But if they pass the test, in keeping with the truth of God’s Word, we can embrace and endorse them wholeheartedly.

California gold miners would only cry “Eureka!” when they found true gold. As Christians, we should be careful to do the same—to proclaim true doctrine and reject all that is false.
