Most of the Christian cults we encounter originate in the US and there is a whole story to be told about that, which we will keep for another time. Many are the product of, or influenced by 19th century Adventism.

They are the heirs of William Miller, a 19th century farmer and Baptist preacher, who prophesied the Second Advent in the 1840s. Miller should be better known because all Adventist cults that follow after him are shaped in some way by him. His influence cannot be overestimated.

William Miller

Born February 1782, in Pittsfield, Massachusetts. His father was Captain Miller, a veteran of the American Revolution. When he was four years old, his family moved to rural Low Hampton, New York. Miller was educated at home by his mother until the age of nine, when he attended the newly established East Poultney District School. There is no record of his having pursued his education beyond the age of eighteen but he read read widely and voraciously.

In 1803, he married Lucy Smith and moved to her nearby home town of Poultney, where he took up farming. He was a pillar of the community, being elected to the office of Constable then, In 1809, to the office of Deputy Sheriff and eventually becoming a Justice of the Peace. Miller served in the Vermont militia and was commissioned a lieutenant on July 21, 1810. He was a reasonably well off, established member of the local community.

Shortly after his marriage, Miller rejected his Baptist heritage and became a Deist, influenced by serious-minded local men who put into his hands works by, Voltaire, David Hume, Thomas Paine, Ethan Allen, and other deistical writers. The Deist view is of a distant God unconcerned with human affairs but a personal experience the war of 1812 was to challenge this view. During one conflict at the Battle of Plattsburgh, in 1814, he described shrapnel shells falling as thick as hailstones. It was during this onslaught, that one shot exploded two feet from him, wounding three of his men, killing another, but leaving Miller alive and untouched.

Miller was persuaded that this, and the victorious outcome for the US forces, was miraculous. His deistic view of a distant God far removed from human affairs was shattered. He later wrote, ‘It seemed to me that the Supreme Being must have watched over the interests of this country in an especial manner, and delivered us from the hands of our enemies… So surprising a result, against such odds, did seem to me like the work of a mightier power than man.’

Miller returned to his family and, eventually, his Baptist faith. This change of heart did not, however, go unchallenged. His Deist friends insisted he should justify his move back to a belief in a personal God involved in the daily affairs of men. He determined to meet the challenge, setting himself the task of closely examining the Bible, verse-by-verse, starting at Genesis 1. It was in this process he finally became convinced of two things, that post-millennialism was unbiblical, and that the time of Christ’s Second Advent was revealed in prophecy.

He began his calculations in Daniel 8:14, ”unto two thousand and three hundred days; then shall the sanctuary be cleansed” (KJV). Using the interpretive principle of a day being equal to a year, he calculated the 2,300 days/years from 457BC and the decree to rebuild Jerusalem given by Ataxerxes I. That period would end in 1843. The cleansing of the sanctuary he interpreted to mean the purification of the earth at Christ’s Second Coming. By 1822 he was confident enough to publish his conclusion.Millerites Poster It was in 1831 he began to give public lectures.

From 1832 to 1834 Miller published letters and articles sharing his research. The interest in his theories became so overwhelming that he published a synopsis of his teachings in a 64- page tract explaining his conclusions. (Evidence from Scripture and History of the Second Coming of Christ, about the Year 1844: Exhibited in a Course of Lectures.)

In 1840 a bi-weekly newspaper, Signs of the Times,  was established to publish his work. His writings had captivated so many that followers of his teachings were referred to collectively as the Millerites. If you lived in the United States in the 1840s you knew about the Millerites.
Miller never set an exact date for the Second Coming. He did narrow the time-period to sometime between March 21, 1843, and March 21, 1844.”

When March 21, 1844, came and went he amended the date suggesting that April 18, 1844 could be the date. Again, April 18, 1844 came and went without incident and Miller responded publicly, writing, “I confess my error, and acknowledge my disappointment; yet I still believe that the day of the Lord is near, even at the door.”

It was actually a man named Samuel S. Snow, a peculiar character who rode about the countryside in a long white robe, calling himself Elijah, who set a date. Snow set an exact date, saying that Christ would return on October 22, 1844. This peculiar chronology was held by an obscure sect of Karaite Jews, whose calendar is different from the Rabbinic calendar. Of course, that date passed without incident and many thousands of Millerites, who had stayed up all night waiting for Christ’s return, found themselves gravely disappointed. Ever since then October 22 is known and marked among Adventists as the Great Disappointment.

Many left the movement, while those who remained divided into two movements. The Open-Door Adventists continued to set dates, trust and preach prophecy, and preach the imminent return of Christ. The Shut-Door movement taught that October 22 had marked a turning point and the opportunity for repentance was passed. No more outreach work was to be done for unbelievers according to this group. It was a 17-year-old Ellen Harmon (later Ellen G White) who claimed to have had a vision in which God had taught her that the probation for people on earth had closed on October 22 and Christ’s return was imminent.

Miller himself died in 1849. His work was the catalyst for the formation of the Adventist Movement. Typically, throughout the century, periodicals appeared with titles like, Signs of the Times, Times and Seasons (a Mormon publication), and, of course, Zion’s Watchtower and Herald of Christ’s Presence. Some of his followers would go on to found the Seventh-day Adventist Church, which we will come on to consider, as well as heavily influence Charles Russell’s Bible Student Movement (eventually Jehovah’s Witnesses).

Jesus said, ‘Concerning the day or the hour no one knows, not even the angels in heaven, nor the Son, but the Father only.’ (Mt.24:36)

Readiness is everything, he went on to teach. This seems to hold no currency with those determined to know what God alone knows. Below is a brief list of prophecies that demonstrate the folly of man when he ignores the counsel of God. If you want to know more about these go to the Wikipedia page where I found the list, which I have shortened for the sake of space. There you will find another list of yet future predictions. Yes, the circus goes on. Jesus’ words for us meanwhile are simply this; ‘You also must be ready, for the Son of Man is coming at an hour you do not expect.’ (Mt.24:44)
